Anti-CREB (Phospho-Ser129)

Y011273 by MBP is a rabbit polyclonal antibody detecting CREB (CREB1) phosphorylated at Serine 129, a non-canonical CK2/DYRK1A-dependent phosphorylation distinct from the canonical transcriptional activation site Ser133. pSer129 modulates CREB stability and sumoylation independently of the CBP/p300 KIX interaction. MW ~43 kDa. WB, IHC, IF, ELISA; human. Research Use Only.
