Protein-protein interactions (PPIs) play a pivotal
role in a multitude of biological processes, with
aberrant activities being closely associated with a range of diseases, including cancer and
neurodegenerative disorders. This invention proposes an innovative geometric deep learning
framework, SpatConv, which directly leverages the raw three-dimensional (3D) coordinates of proteins
and features extracted from the pre-trained ProtT5 model as inputs, thereby eliminating the need for
any precomputed manual features. SpatConv constructs local coordinate systems that adhere to SE(3)
equivariance, enabling precise mapping of residue distribution and integration of multi-scale
protein features. The use of spatial graph convolution techniques facilitates efficient message
passing and feature updating.
