CREB is a beta ZIP transcription factor that activates target genes through cAMP response elements. CREB is able to mediate signals from numerous physiological stimuli, resulting in regulation of a broad array of cellular responses. While CREB is expressed in numerous tissues, it plays a large regulatory role in the nervous system. CREB is believed to play a key role in promoting neuronal survival, precursor proliferation, neurite outgrowth and neuronal differentiation in certain neuronal populations. Additionally, CREB signaling is involved in learning and memory in several organisms. CREB is able to selectively activate numerous downstream genes through interactions with different dimerization partners. CREB is activated by phosphorylation at Ser133 by various signaling pathways including Erk, Ca2+ and stress signaling. Some of the kinases involved in phosphorylating CREB at Ser133 are p90RSK, MSK, CaMKIV and MAPKAPK-2.

Human cyclic AMP responsive element binding protein-1 (CREB-1, p43). By Western blot it shows a major band at 46 kDa when assayed against a lysate of 1 x 106 Raji B cells. Minor bands at 75 kDa and 43 kDa may be noted. Partial reactivity to CREM-1 protein. May react non-specifically with other proteins.

CREB-1 (p43) peptide corresponding to the N-terminal (aa 5-45) of human protein conjugated to KLH.
