Proteomics

Proteomics

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Cryo-electron Microscopy

Cryo-electron Microscopy

Conventional electron microscopy (EM) involves dehydration, fixation, and staining of biological samples, which distorts the native state of biological molecules and results in several artifacts. Also, the high-energy electron beam damages the sample and makes it difficult to obtain high-resolution images. These issues can be addressed using cryo-EM, which uses frozen samples and gentler electron beams. The technique was developed by Jacques Dubochet, Joachim Frank, and Richard Henderson, for...

Background:

Single-domain antibodies (nanobodies) are crucial in bio-therapeutics due to their small size.
Nanobody thermostability is critical for their effective application in biotechnology.
Predictive models are needed to optimize nanobody design and stability.

Purpose of the Study:

To introduce TEMPRO, a novel computational approach for predicting nanobody melting temperatures (T_m).
To leverage integrated biophysical features and protein embeddings for accurate T_m estimation.
To provide a tool for enhancing nanobody thermostability for therapeutic development.

Main Methods:

Integrated Evolutionary Scale Modeling (ESM) embeddings, NetSurfP3 structural predictions, AlphaFold2 pLDDT scores, and physicochemical properties.
Developed a predictive model using a dataset of 567 unique nanobody sequences with experimental T_m values.
Validated model performance against internal data and the NbThermo database, including external nanobody sets.

Main Results:

TEMPRO accurately predicts nanobody T_m with a mean absolute error (MAE) of 4.03 °C and root mean squared error (RMSE) of 5.66 °C.
Protein embeddings demonstrated high efficacy in predicting nanobody thermostability.
Model validation confirmed its reliability for nanobodies not included in the training set.

Conclusions:

TEMPRO serves as a valuable tool for optimizing nanobody thermostability in biomedical and therapeutic applications.
The study highlights the utility of protein embeddings for predicting protein properties.
This predictive approach facilitates broader applications of nanobodies in downstream protein analyses.
