title: Chromosomal localization of the human gene for brain Ca2+/calmodulin-dependent protein kinase type IV.
abstract: Cloned cDNAs have been identified as corresponding to a new brain Ca2+/calmodulin-dependent protein kinase. On the basis of structural and immunological features, we refer to this new kinase as CaM Kinase IV. Two cDNA clones were used to identify CaM Kinase IV: The downstream clone, lambda ICM-1, contains the sequence encoding the calmodulin-binding site and the second clone, lambda ICM-2, encodes a partial amino acid sequence similar to the catalytic domain of several known protein kinases. Within the calmodulin-binding site a stretch of 8 amino acids (and 9 of 10) is identical to the corresponding site in the subunits of CaM Kinase II. Southern blot analysis shows the CaM Kinase IV gene is single copy in the mouse and human genomes. Synteny analysis of Southern blot data of DNA from hamster--human hybrid cells shows that the gene is present in human chromosome 5. Hybridization of cDNA probes to metaphase spreads of human chromosomes indicates that the gene is most likely located within the region of bands q21 to q23 of chromosome 5.
