OGT-PIN Header Image

Interactions between proteins are essential to any cellular process and constitute the basis for molecular networks that determine the functional state of a cell. Defining the interactome of OGT, the sole enzyme adding the O-GlcNAc onto its target proteins, can facilitate studies in OGT biology, protein O-GlcNAcylation, functional elucidation of proteins/pathways/processes, drug development, and others.


OGT Protein Interaction Network (OGT-PIN) is a curated and comprehensive database of experimentally identified interaction proteins of OGT and its orthologues in multiple species studied in the past several decades.

The current version: OGT-PIN_2.0
