Invitrogen™ c-Fos Recombinant Rabbit Monoclonal Antibody (RM374)

Description

Specificity: reacts to human Proto-oncogene c-Fos. It may also react to mouse and rat c-Fos, as predicted by immunogen homology. Recombinant rabbit monoclonal antibodies are produced using in vitro expression systems. The expression systems are developed by cloning in the specific antibody DNA sequences from immunoreactive rabbits. Then, individual clones are screened to select the best candidates for production. The advantages of using recombinant rabbit monoclonal antibodies include: better specificity and sensitivity, lot-to-lot consistency, animal origin-free formulations, and broader immunoreactivity to diverse targets due to larger rabbit immune repertoire.

FBJ murine osteosarcoma viral oncogene homolog is commonly known as Cellular protooncogene Fos (c-Fos). It belongs to the fos transcription factor family and is encoded by the C-FOS gene located on chromosome 14. c-Fos heterodimerizes with c-Jun to form the Activator Protein -1 (AP-1) transcription factor which regulates transcription of several genes that play an important role in cellular signal transduction, cell proliferation and differentiation. c-Fos has been shown to be phosphorylated by various stimuli including growth factors and insulin at atleast seven different sites. The best known upstream kinase for phosphorylation at Threonine 232 is ERK MAPK which regulates localization of c-Fos to the nucleus and is thus important for c-Fos induced transcriptional activity.
