Prohibitin 2 Antibody

Western blot shows lysates of HEK293 human embryonic kidney cell line, K562 human chronic myelogenous leukemia cell line, HeLa human cervical epithelial carcinoma cell line, and Raji human Burkitt's lymphoma cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human/Mouse/Rat Prohibitin 2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4794) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Prohibitin 2 at approximately 37 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background

Prohibitin 2 (PHB2; also B-cell receptor-associated protein BAP37 and REA) is a 37 kDa, ubiquitous member of the prohibitin family of molecules. PHB2 is found in multiple intracellular compartments. It is suggested to be a component of an inner mitochondrial membrane complex and a nuclear repressor of the estrogen receptor (ER). Human PHB2 is 299 amino acids (aa) in length. It contains a mitochondrial localization signal (aa 1‑50), two ER repressor domains (aa 19‑49 and aa 150‑174), and a central coiled-coil domain (aa 190‑238). There may be one splice variant that shows a premature truncation after aa 289. Over aa 89‑299, mouse and rat PHB2 are 100% identical to human PHB2.
