Phb Gene Summary [Rat]
Predicted to enable several functions, including complement binding activity; histone deacetylase binding activity; and protein heterodimerization activity. Involved in several processes, including female gonad development; positive regulation of phosphatidylinositol 3-kinase/protein kinase B signal transduction; and positive regulation of smooth muscle cell proliferation. Located in mitochondrial outer membrane. Is active in GABA-ergic synapse; glutamatergic synapse; and postsynaptic density. Is extrinsic component of presynaptic active zone membrane. Biomarker of urinary bladder cancer. Human ortholog(s) of this gene implicated in breast cancer and sporadic breast cancer. Orthologous to human PHB1 (prohibitin 1).

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