CaMKIIα/δ (M281) polyclonal antibody

The Ca2+/calmodulin-dependent protein kinases (CaM kinases) comprise a structurally related subfamily of serine/threonine kinases which include CaMKI, CaMKII and CaMKIV. CaMKII is an ubiquitously expressed serine/threonine protein kinase that is activated by Ca2+ and calmodulin (CaM) and has been implicated in regulation of the cell cycle and transcription. There are four CaMKII isozymes, designated α, β, γ and δ, which may or may not be co-expressed in the same tissue type. CaMKIIα is autophosphorylated on Thr 286 upon the binding of the Ca2+/CaM complex to the autoinhibitory domain of CaMKII. This process is called Ca2+/CaM trapping, which is thought to be involved in the synaptic encoding of information.
