Transcripts
so Google deepmind and isomorphic Labs
have just surprised the industry by
releasing Alpha fold 3 and announcing
how good it truly is so it says Alpha
fold 3 predicts the structure and
interactions of all of life's molecules
you can see here it states introducing
Alpha 3 a new AI model developed by
Google Deep Mind and isomorphic Labs by
accurately predicting the structure of
proteins DNA RNA ligans and more and how
they interact we hope it will transform
our understanding of the biological
world and Drug Discovery so you have to
think about it like this in every cell
of every living thing plant animals even
us there are literally billions of these
microscopic machines and these machines
are made up of proteins DNA and other
funky molecules and the thing is is that
none of these pieces work alone they're
all kind of interacting combining in
millions of ways and only by seeing that
interaction can we actually understand
understand how life works and this is
where Alpha 3 comes in they literally
just published a pcture in nature
magazine which we'll get into later in
which they talk about this amazing new
AI model and this model can literally
predict the structure of life's very
molecules and even how they interact
with crazy good accuracy and we're
actually talking a significant leap on
what we could do before and the crazy
thing is is that this is probably about
to show us how all those crazy crazy
machines fit together why they behave
the way they do and this is the key to
understanding everything from diseases
to how plants grow and how to fix
problems or build new awesome stuff and
the details of this are pretty pretty
crazy and it's pretty incredible that
they've managed to build upon the
success of alpha Fall 2 which was the
one that changed the game in
understanding proteins and researchers
everywhere actually do use it think of
malaria vaccines cancer research the
entire ire whole deal and Alpha for's
already been such a GameChanger it's
even one major science Awards and Alpha
for 3 it actually goes Way Beyond just
proteins to all sorts of biomolecules
think eco-friendly materials stronger
crops supercharged medicine this is
pretty much next level science with the
power to change the world so how does
this actually work so given a list of
input molecules Alpha fault 3 generates
their joint 3D structure revealing how
they all fit together it models large
biomolecules such as proteins DNA and
RNA as well as small molecules also
known as ligans a category encompassing
many different drugs and they can model
chemical modifications to these
molecules which control the healthy
functioning of cells that when disrupted
can lead to the disease we also see that
Alpha folds 3's capabilities come from
its next Generation architecture and
training that now covers all of life's
molecules at the core of the model is an
improved version of the Evo former
module which is essentially a module
that kind of learns the grammar of
protein folding by studying evolutionary
examples and then uses that knowledge to
predict the 3D structure of new amino
acid sequences much like how we can kind
of predict the meaning of a new sentence
after learning the grammar of of a
language and it's a deep learning
architecture that underpinned Alpha
folds 2's incredible performance and
after processing the input Alpha for 3
assembles its predictions using a
diffusion Network akin to those found in
AI image generators and the diffusion
process starts with a cloud of atoms and
over many steps converges on its final
most accurate molecular structure now
here's where we have one of the
predictions so this in well in this case
what we do have here is we have the
ground truth shown in Gray and then we
have the real one shown in the actual
colors so in this example what we do
have here is we have us looking at the
spike of a protein of a common cold
virus the spike protein is a part of the
virus that helps it infect our cells and
the AI model actually accurately
predicted how this Spike protein
interacts with antibodies which are the
immune systems defense proteins that
attach the virus and neutralize it and
of course simple sugars in this
prediction that you're currently seeing
on screen the spike protein is in blue
the antibodies which try to stop the
virus are shown in turquoise so the
simple sugars are also shown in yellow
and these predictions essentially
closely match what scientists have
observed in real life experiments which
are shown in Gray by using animations of
this interaction scientists can then see
exactly how the virus actually interacts
with antibodies and sugars and this
information is crucial because
understanding how these immune system
processes helps us figure out how to
fight different viruses including
covid-19 leading to the potential of
better treatments and Alpha fold 3 saves
so much time by providing accurate
predictions that would otherwise require
lengthy and expensive laboratory
equipments and it does this because
determining the 3D structure of proteins
using experimental methods like x-ray
crystallography or cryo electron
microscopy can take months or even years
and alphaa 3 can predict these
structures in literally hours or days
and with predicted structures available
scientists can then focus on the most
promising drug Target or biological
questions without spending time
exploring dead ends and this allows
researchers to test hypothesis so
there's hypothesis generation where it
can generate new hypotheses about how
biological molecules function or
interact and researchers can then test
these hypotheses directly reducing the
need for broad exploratory studies now
there was also another example here in
which we can see Tim 3 This Is A protein
that researchers are studying because it
might be useful SL a useful Target for
cancer treatment and scientists found a
way to create small molecules that could
stick to this protein and potentially
block the harmful effects now before
this study there weren't any clear
images showing how these small drug-like
molecules would actually fit into the
Tim 3's structure
and without this information designing
effective drugs was pretty challenging
so essentially Alpha fold 3 comes in
scientists use Alpha fold 3 to predict
what Tim 3 would look like when these
small molecules bind to it and they only
provided the AI with the protein
sequence which is essentially the recipe
and a simple description of the drug
like molecules so that's where we get to
the outcome so Alpha fold 3 actually
predicted how these molecules would fit
together perfectly into the pocket of
the Tim 3 protein aligning almost
exactly with the structures that
scientists discovered through
experiments it also showed that without
these drug molecules present the pocket
actually looked different proving that
Alpha fold 3 can actually recognize
changes in protein shapes when other
molecules are around and this
essentially means that Alpha fold 3 can
predict how drug molecules will interact
with proteins more accurately than ever
before and this is going to lead to fast
and more efficient drug Discovery
helping scientists developed better
treatments for cancer and other diseases
and of course it makes sense to talk
about isomorphic Labs so one of the
things that they talk about leading this
drug drug Discovery at isomorphic Labs
is that alphafold 3 is 50% more accurate
than the best traditional methods on the
pose Busters Benchmark without needing
the input of any structural information
making alphaa 3 the first AI system to
surpass physics based tools for
biomolecular structure prediction and
isomorphic Labs is using alphafold 3 to
accelerate and improve the success of
drug design by helping understand how to
approach new disease targets and
developing novel ways to pursue existing
ones that were previously Out Of Reach
they also talk about how we can now
create and test hypotheses at the atomic
level and produce highly accurate
structure predictions within seconds
standing in STK contrast to the months
or even years require to experimentally
determine answers to similar questions
now they also talk about how they're
using this they state that already we
are using alphafold 3 dayto day our
scientists have seen that designing
small molecules against alphafold 3's
structural predictions helps create
designs that bind effectively to a
Target protein the improved structural
accuracy of protein to protein
interfaces with Alpha fall 3 opens up
the possibility of Designing new
treatment modalities such as antibodies
or other therapeutic proteins and a
richer understanding of a novel Target
can be achieved by looking at the
structure of Targets in their full
biological context in complex with other
protein binding Partners DNA RNA and
ligand co-actors and of course there was
a paper that was released with the alpha
fold 3 release however this is currently
an accelerated article preview an AAP
which is a version of a scientific
article that's published online before
it appears in a traditional print
journal and it basically just means that
it's just designed to get important
research findings out to scientists and
the public as quickly as possible and
they kind of skip some of the editing
and formatting that can actually slow
down a traditional Journal publication
and that means that there is like a
watermark on each page to remind you
that they aren't final the final
polished version now here's where we
actually talk about the main thing which
is of course the alpha fold server so
Google actually launched this tool that
actually helps you do this stuff so
scientists can actually use this for
free there's no fancy subscription
needed and basically with a few clicks
any battes can use Alpha fall 3 to make
models of proteins DNA RNA and other
important molecules and this is pretty
huge because the alphaa server lets
scientists quickly come up with new
ideas to test out in the lab and this
cuts out the time on wasting guesswork
so just just picture your science
projects going way faster and remember
this used to take you a huge amount of
time and now all of that is being saved
so this is the quick trailer I'll leave
you guys with this and if you need any
of the links there will be either at a
top comment or a link in the description
