Structures of distantly related interacting protein homologs are less divergent than non‐interacting homologs

open access: yesFEBS Open Bio, 2022
Homologous proteins can display high structural variation due to evolutionary divergence at low sequence identity. This classical inverse relationship between sequence identity and structural similarity, established many years ago, has remained true ...

Structural Image De-Identification for Privacy-Preserving Deep Learning

open access: yesIEEE Access, 2020
Due to the risk of data leakage while training deep learning models in a shared environment, we propose a new privacy-preserving deep learning (PPDL) method using a structural image de-identification approach for object classification.
