IHC staining with Alexa Fluor® 647 anti-c-Fos Phospho (Ser32) was performed on formalin-fixed paraffin-embedded human brain cortex following antigen retrieval using Citrate buffer (Cat. No. 420902). The tissue sections were incubated with Alexa Fluor® 647 secondary antibody only (panel A) or with Alexa Fluor® 647 anti-c-Fos Phospho (Ser32) (clone A22009C) (panel B). Nuclei were counterstained with DAPI (Cat. No. 422801).

Description

The proto-oncogene c-Fos is the human homolog of the retroviral v-Fos oncogene, and is a member of the Fos family of transcription factors. c-Fos forms heterodimers with proteins of the Jun family of transcription factors to form the Activator Protein-1 complex (AP-1). This complex is involved in critical cellular processes such as inflammation, cell proliferation, differentiation, survival, hypoxia, bone development and angiogenesis which suggests c-Fos is an important therapeutic target for cancer, vascular remodeling, acute inflammation and autoimmune diseases.  In addition, increases in c-Fos expression and activation are associated with neuronal activity induced by psychoactive drugs. Expression of c-Fos is rapid and transitory, and phosphorylation at residues Ser32 and Thr232 by Erk5 increases protein stability and nuclear localization.

Antigen Details

Structure
c-Fos is a 380 amino acid length protein. It has a leucine zipper domain that allows it to form heterodimers with members of the Jun family proteins.
Distribution

Non-phosphorylated forms can be found in the endoplasmic reticulum. However, after activation/phosphorylation the protein is translocated to the nucleus.

Function
c-Fos is a subunit of the AP-1 transcription factor. The half-life of the protein is short; however, phosphorylation induces protein stability and translocation to the nucleus.
Interaction
c-Fos interacts with members of the Jun family proteins to form the AP-1 transcription factor.
Ligand/Receptor
As a part of the transcription factor AP-1, it binds to specific DNA sequences to regulate gene transcription
