Phb2 Gene Summary [Rat]
Predicted to enable amide binding activity; protein dimerization activity; and sphingolipid binding activity. Involved in cellular response to hypoxia; cellular response to retinoic acid; and negative regulation of apoptotic process. Located in axon and mitochondrion. Is active in several cellular components, including GABA-ergic synapse; glutamatergic synapse; and postsynaptic density. Orthologous to human PHB2 (prohibitin 2).

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 Phb2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
