Anti-phospho-c-Jun (Ser73) Antibody

c-Jun is a component of the transcription factor AP-1 that binds and activates transcription at TRE/AP-1 elements and appears to be a major downstream target of the SAPK/JNK signaling pathway. The transcriptional activity of c-Jun is regulated by phosphorylation at Ser63 and Ser73. Extracellular signals including growth factors, transforming oncoproteins and UV irradiation stimulate phosphorylation of c-Jun at Ser63/73 and activate c-Jun dependent transcription. Mutation of Ser63/73 renders c-Jun nonresponsive to mitogenic and stress induced

signaling pathways. The MAP kinase homologue, SAPK/JNK, binds to the N-terminal region of c-Jun and phosphorylates c-Jun at Ser63/73. In addition, the activity of SAPK/JNK is stimulated by the same signals that activate c-Jun.

This antibody detects phospho-c-Jun. May also detect phospho-JunD in properly treated cells since the sequence homology is identical (13/13).

KLH-conjugated linear peptide corresponding to the human Phospho-C-Jun (Ser73) near the N-terminus.

Anti-phospho-c-Jun (Ser73) Antibody is a Rabbit Polyclonal Antibody for detection of phospho-c-Jun (Ser73) also known as Activator protein 1 & has been validated in ICC, IP & WB.
