Prohibitin-2 (UniProt Q99623; also known as B-cell associated protein, B-cell receptor-associated protein BAP37, BCAP37, D-prohibitin, PHB2, Repressor of estrogen receptor activity) is encoded by the PHB2 (also known as BAP, REA) gene (Gene ID 11331) in human. Prohibitins are assembled into a ring-like PHB complex with 16-20 alternating Phb1 and Phb2 subunits in the inner mitochondrial membrane, where they function as chaperone for respiration chain proteins or as important structural scaffold for optimal mitochondrial morphology and function. Prohibitins are also reported to modulate transcriptions by interacting with various transcription factors, including nuclear receptors. Upregulated expression of prohibitins, septin 9, neurabin 1, and other cytoskeletal and functional proteins is found at the glutathione S-transferase placental-form-positive (GST-P+) hepatocellular carcinoma (HCC) foci during initiation and/or promotion stages of rat hepatocarcinogenesis, implicating an involvement of prohibitins in the neoplastic transformation of rat liver preneoplastic lesions.
