Abstract

We report here the complete cDNA sequence, genomic mapping, and immunolocalization of the first human member of the protein kinase C inhibitor (PKCI-1) gene family. The predicted human protein (hPKCI-1) is 96% identical to bovine and 53% identical to maize members, indicating the great evolutionary conservation of this protein family. The hPKCI-1 gene (HGMV- approved symbol PRKCNH1) maps to human chromosome 5q31.2 by fluorescence in situ hybridization. Indirect immunofluorescence shows that hPKCI-1 localizes to cytoskeletal structures in the cytoplasm of a human fibroblast cell line and is largely excluded from the nucleus. The cytoplasmic localization of hPKCI 1 is consistent with a postulated role in mediating a membrane-derived signal in response to ionizing radiation.
