Anti-phospho-c-Myb (Thr486)

This affinity-purified antibody is directed against the phosphorylated form of mouse c-Myb protein at the pT486 residue. Antiserum was first purified against the phosphorylated form of the immunizing peptide.  The resultant affinity purified antibody was then cross adsorbed against the non-phosphorylated form of the immunizing peptide.  Reactivity occurs against mouse c-Myb pT486 protein and the antibody is specific for the phosphorylated form of the protein.  This antibody reacts with endogenous c-Myb protein and also SUMOylated overexpressed c-Myb protein in transfected Cos7 cells. Reactivity with non-phosphorylated mouse c-Myb is minimal by ELISA and western blot. A BLAST analysis was used to suggest reactivity with c-Myb from mouse based on a 100% homology with the immunizing sequence.  Expect reactivity with c-Myb from rat, pig, human, horse, platypus, opossum, orangutan, spider monkey, bonobo, gorilla, and chimpanzee, with a v-myb myeloblastosis viral oncogene homolog, all isoforms (also avian version) from human, and with a protooncogene c-myb, and a v-myb myeloblastosis viral oncogene homolog (avian), both from cattle, all based on a 93% homology with the immunizing sequence.  Cross-reactivity with c-Myb from other sources has not been determined. Protein function: Transcriptional activator, DNA-binding protein that specifically recognize the sequence 5'-YAAC[GT]G-3'. Plays an important role in the control of proliferation and differentiation of hematopoietic progenitor cells. [The UniProt Consortium]
