While most Fos proteins exist as a single isoform, the FosB protein exists as two isoforms: fμll-length FosB and a shorter form, FosB2 (Delta FosB), that lacks the carboxy-terminal 101 amino acids (1-3). The expression of Fos proteins is rapidly and transiently induced by a variety of extracellμlar stimμli including growth factors, cytokines, neurotransmitters, polypeptide hormones, and stress. Fos proteins dimerize with Jun proteins (c-Jun, JunB, and JunD) to form Activator Protein-1 (AP-1), a transcription factor that binds to TRE\/AP-1 elements and activates transcription. Fos and Jun proteins contain the leucine-zipper motif that mediates dimerization and an adjacent basic domain that binds to DNA. The various Fos\/Jun heterodimers differ in their ability to transactivate AP-1 dependent genes. In addition to increased expression, phosphorylation of Fos proteins by Erk kinases in response to extracellμlar stimμli may further increase transcriptional activity (4-6). Phosphorylation of c-Fos at Ser32 and Thr232 by Erk5 increases protein stability and nuclear localization (5). Phosphorylation of FRA1 at Ser252 and Ser265 by Erk1\/2 increases protein stability and leads to overexpression of FRA1 in cancer cells (6). Following growth factor stimμlation, expression of FosB and c-Fos in quiescent fibroblasts is immediate, but very short-lived, with protein levels dissipating after several hours (7). FRA1 and FRA2 expression persists longer, and appreciable levels can be detected in asynchronously growing cells (8). Deregμlated expression of c-Fos, FosB, or FRA2 can resμlt in neoplastic cellμlar transformation, however, Delta FosB lacks the ability to transform cells (2, 3).\u003c\/p\u003e\n\n\u003cp\u003eCategory: Primary Antibody\u003c\/p\u003e\n\n\u003cp\u003eReactivity: Human, Mouse, Rat\u003c\/p\u003e\n\n\u003cp\u003eHost: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eApplications: WB, IHC\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: p55, AP-1, C-FOS,\u003c\/p\u003e \n\n\u003cp\u003eClonality: Polyclonal\u003c\/p\u003e\n\n\u003cp\u003eConjugate: Unconjugated\u003c\/p\u003e\n\n\u003cp\u003eModification: Phosphorylation\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: A phospho specific peptide corresponding to residues surrounding T232 of human FOS.\u003c\/p\u003e\n\n\u003cp\u003eDilution: WB 1:500 - 1:1000\u003cbr\u003e\nIHC 1:50 - 1:200\u003c\/p\u003e\n\n\u003cp\u003ePurification: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is \u0026gt; 95% (by SDS-PAGE).\u003c\/p\u003e\n\n\u003cp\u003eSpecificity: c-Fos (phospho-T232) polyclonal antibody detects endogenous levels of c-Fos protein only when phosphorylated at Thr232.\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight: ~ 62 kDa\u003c\/p\u003e\n\n\u003cp\u003ePathway: MAPK Erk in Growth and Differentiation Pathway,\u003c\/p\u003e \n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.
