Anti-CaM Kinase IIalpha (CaMKIIalpha) antibody produced in rabbit (C15-1346-740)

General description

Ca²⁺/Calmodulin dependent protein kinase II (CaMKII) belongs to the family of Ser/Thr protein kinases including CaMKI and CaMKIV. CaM kinase II is one of the most abundant protein kinases in the mammalian brain, with the highest expression in neurons of the hippocampus and the cerebral cortex. CaMKII consists of a family of four related isoforms CaMK IIα, CaMK IIβ, CaMK IIγ and CaMK IIδ. The CaMK II α and β isoforms are predominantly expressed in the brain, localized mainly in the cytosol and postsynaptic densities (PSDs), whereas the CaMKII γ and δ isoforms are expressed in all tissues. CaMKII contains a catalytic and regulatory domain. The regulatory domain consists of an autoinhibitory and calmodulin binding site.

Specificity

The antibody does not cross-react with CaMKIIβ, γ and δ isoforms (60 kDa). Anti-CaM Kinase IIα specifically binds to CaM Kinase IIα (50kDa) in human, mouse, rat and chicken. CaM Kinase IIα immunizing peptide specifically inhibits the staining of CaM Kinase IIα in immunoblotting.

Immunogen

Peptide corresponding to amino acids 461-478 of rat CaM Kinase Iiα, conjugated to KLH. This sequence is identical in human, mouse and chicken CaMKIIα has limited homology (50-60%) with CaM Kinase IIβ, γ and δ subunits.

Application

Anti-CaM Kinase IIα (CaMKIIα) antibody has been used:

• in immunolabelling
• in western blotting
• in immunoprecipitation
• in immunoblotting

Biochem/physiol Actions

CaMKII is involved in many cellular functions in response to Ca²⁺ signaling, including synthesis and secretion of neurotransmitters, axonal transport, long term potentiation (LTP) and spatial learning, receptor function and regulation of gene expression. CaMKII plays a critical role in LTP, a cellular model of learning and memory. In the CNS, postsynaptic Ca²⁺ influx triggers rapid autophosphorylation and stable activation of CaMKII in a Ca²⁺/calmodulin dependent manner at a threonine residue in the autoinhibitory domain. Autophosphorylation of CaMKIIα at Thr²⁸⁶ has been shown to be required for LTP and learning.
