Description_x000D_ Biochem/physiol Actions_x000D_ CAMK2β belongs to the serine/threonine protein kinase family and to the type II multifunctional Ca2+/calmodulin-dependent protein kinase subfamily. CAMK2β showed wide tissue and cell distribution, and one of CAMK2β variant predominated in adult brain. The ratio of CAMK2α and CAMK2β protein levels were inversely related during activity in hippocampal neurons. CAMK2β is a prominent kinase in the central nervous system and may function in long-term potentiation and neurotransmitter release._x000D_ Physical form_x000D_ Supplied in 50mM NaPhosphate pH 7.0, 300 mM NaCl, 150 mM imidazole, 0.1mM PMSF, 0.2 mM DTT, 25% glycerol._x000D_ Legal Information_x000D_ PRECISIO is a registered trademark of Sigma-Aldrich Co.
