Rabbit Polyclonal Antibody

Manufacturer:  Invitrogen PA1830

Catalog No. PA1830

Add to cart



PA1-830 detects cFos from mouse and human cells and tissues. PA1-830 has been successfully used in Western blot and immunofluorescence procedures. By Western blot, this antibody detects an ~60 kDa protein representing cFos in NIH 3T3 serum stimulated cells. The PA1-830 immunogen is a synthetic peptide corresponding to residues S(4) G F N A D Y E A S S S R C(17) of human cFos. This sequence is completely conserved in mouse cFos. Reconstitute with 200 µL of PBS (1 mg/mL).

Cellular oncogenes, or proto-oncogenes, play pivotal roles in cellular communication pathways that regulate normal growth, development and differentiation. The cellular oncogene families fos and jun encode nuclear proteins that can function as transcription factors. The fos family of nuclear oncogenes encode cFos, FosB, (fos-related antigen) Fra1, and Fra2. Fos and Jun dimerize to form Activator Protein-1 (AP-1), a transcriptional factor that binds to the 12-O-tetradecanoylphorbol 13-acetate (TPA) response element (TRE) of several cellular and viral genes including human collagenase, metallothionein IIa, stromelysin, interleukin 2, SV40 and polyoma. Fos and Jun contain the ‘leucine-zipper’ motif that allows for dimerization and an adjacent basic domain required for biological activity. The functionally active form of Fos is in a heterodimer with a member of the Jun family. While Jun family members can form functional homodimers, studies indicate that Fos family members do not self-associate and therefore do not bind DNA on their own. The various dimers differ in their ability to transactivate AP-1 dependent genes.
