| CaMKII alpha, the alpha subunit of Ca2+calmodulin-dependent protein kinase II is part of a family of multifunctional protein kinases which play a major role in Ca2+-mediated signal transduction. CaMKIIalpha is expressed in many different tissues but is specifically found in the neurons of the forebrain and its mRNA is found within the dendrites as well as the soma of the neuron. The neuronal CaMKII consists of two major subunits of 52 and 60kD which are encoded by alpha-and beta-CaMKII genes, respectively. Additional isoforms are generated by alternative splicing of these as well as of the ubiquitious gama-and delta-CaMKII genes. Each subunit has an ATP-binding domain (arginine-X-X-serune/threonine), consensus phosphorylation site, catalytic domain, and a centrally located regulatory domain which has calmodulin binding activity (2–6). Activation and autophosphorylation of CaMKII may regulate numerous neuronal processes which includes two forms of synaptic plasticity, long term potentiation and long term depression (7,8). Neuronal CAMKII subunits assemble as large multimeric holoenzymes. The C-terminal association domains of 6–12 subunits assemble into a central globular structure from which the N-terminal catalytic/regulatory domains extend radially like petals of a flower (9). The subunit composition of the rat forebrain CaMKII holoenzyme consists of hetermers composed of alpha and beta subunits at a ratio of 2:1 and homomers composed of only alpha subunits. The association of CaMKII subunits leads to the positioning of their catalytic/regulatory domains in close proximity and the neighboring calmodulin-bound subunits cooperate to rapidly phosphorylate each other (10–12) Autophosphorylation also enables CaMKII to attain an enhanced affinity for NMDA receptors in postsynaptic densities (13–15) | | | Catalog # | C1035-25P | | Applications | Western Blot (Colorimetric) (16): 0.1ug/ml 1:1,000 | | RIA (Quantitative WB) (1): 3-5ug/ml | | Immunohistochemistry (1) | | Positive Controls | Rat Brain Tissue Extract | | Mouse Brain Tissue Extract | | CAS Number | n/a | | Clone Type | Monoclonal | | Isotype | IgG1 | | Clone No | 4E22 | | Host | Mouse | | Source | Rat | | Form | Supplied as a liquid in PBS, pH 7.2 0.1mM PMSF, in 50% glycerol. | | Purity | Purified by Protein G affinity chromatography. | | Immunogen | Partially purified rat CaMKII | | Specificity | Detects a ~50-60kD protein, corresponding to the apparent molecular mass of CaMKII alpha-subunit on SDS-PAGE immunoblots, in samples from mouse, rat and bovine. Both the phosphorylated and non-phosphorylated forms are recognized. Expected reactivity includes the alpha, delta and gamma isoforms, but not the beta isoform. | | | Important Note | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological. |
