Anti- c-fos抗体
From:ABCAM
Catalog Number :RS- 0469R
Quantity size : 0.1ml (dilute with pH 7.4 0.01 M PBS or antibody diluent ) Background: The Fos gene family consists of 4 members: FOS, FOSB, FOSL1, and FOSL2. These genes encode leucine zipper proteins that can dimerize with proteins of the JUN family, thereby forming the transcription factor complex AP-1. As such, the FOS proteins have been implicated as regulators of cell proliferation, differentiation, and transformation. In some cases, expression of the FOS gene has also been associated with apoptotic cell death. [provided by RefSeq, Jul 2008].
Function : Nuclear phosphoprotein which forms a tight butnon-covalently linked complex with the JUN/AP-1 transcriptionfactor. In the heterodimer, FOS and JUN/AP-1 basic regions eachseems to interact with symmetrical DNA half sites. On TGF-betaactivation, forms a multimeric SMAD3/SMAD4/JUN/FOS complex at theAP1/SMAD-binding site to regulate TGF-beta-mediated signaling. Hasa critical function in regulating the Has a critical function inregulating the development of cells destined to form and maintainthe skeleton. It is thought to have an important role in signaltransduction, cell proliferation and differentiation.Subunit : Heterodimer; with JUN (By similarity). Interacts withMAFB. Component of the SMAD3/SMAD4/JUN/FOS complexrequired for syngernistic TGF-beta-mediated transcription at theAP1 promoter site. Interacts with SMAD3; the interaction is weakeven on TGF-beta activation. Interacts with MAFB. Interacts withDSIPI; this interaction inhibits the binding of active AP1 to itstarget DNA.Subcellular Location : Nucleus.Post-translational modifications : Phosphorylated in the C-terminal upon stimulation by nervegrowth factor (NGF) and epidermal growth factor (EGF).Phosphorylated, in vitro, by MAPK and RSK1. Phosphorylation on bothSer-362 and Ser-374 by MAPK1/2 and RSK1/2 leads to proteinstabilization with phosphorylation on Ser-374 being the major sitefor protein stabilization on NGF stimulation. Phosphorylation onSer-362 and Ser-374 primes further phosphorylations on Thr-325 andThr-331 through promoting docking of MAPK to the DEF domain.Phosphorylation on Thr-232, induced by HA-RAS, activates thetranscriptional activity and antagonizes sumoylation.Phosphorylation on Ser-362 by RSK2 in osteoblasts contributes toosteoblast transformation (By similarity). [PTM] Constitutively sumoylated by SUMO1, SUMO2 and SUMO3.Desumoylated by SENP2. Sumoylation requires heterodimerization withJUN and is enhanced by mitogen stimulation. Sumoylation inhibitsthe AP-1 transcriptional activity and is, itself, inhibited byRas-activated phosphorylation on Thr-232.Similarity : Belongs to the bZIP family. Fos subfamily.
Contains 1 bZIP domain.Database links : UniProtKB/Swiss-Prot: P01100.1
