Atg4b Gene Summary [Rat]
Predicted to enable cysteine-type endopeptidase activity; protein-phosphatidylethanolamide deconjugating activity; and scaffold protein binding activity. Involved in positive regulation of protein catabolic process. Predicted to be located in several cellular components, including autophagosome; endoplasmic reticulum; and mitochondrion. Predicted to be active in autophagosome membrane. Orthologous to human ATG4B (autophagy related 4B cysteine peptidase). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Atg4b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
