Human Gene ID：2353

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 mul
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 activat
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
Similarity：Belongs to the bZIP family. Fos subfamily.
Contains 1 bZIP domain.
