Description:
The calcium-calmodulin-dependent protein kinase II is a major component of brain synaptic junctions and has been proposed to play a variety of important roles in brain function. A complementary DNA representing a portion of the smaller 50-kilodalton subunit of the rat brain enzyme has been cloned and sequenced. The calmodulin-binding region has been identified and a synthetic analog prepared that binds calmodulin with high affinity in the presence of calcium. Like the 50-kilodalton kinase polypeptide, the concentration of the messenger RNA varies both neuroanatomically and during postnatal development of the brain. The broad tissue and species cross-reactivity of the complementary DNA suggests that the 50-kilodalton subunit found in rat brain is evolutionarily conserved and is the product of a single gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hanley, R M -- Means, A R -- Ono, T -- Kemp, B E -- Burgin, K E -- Waxham, N -- Kelly, P T -- New York, N.Y. -- Science. 1987 Jul 17;237(4812):293-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3037704" target="_blank"〉PubMed〈/a〉
