title: Molecular cloning of the myelin specific enzyme 2',3'-cyclic-nucleotide 3'-phosphohydrolase.
abstract: We describe the isolation of cDNA clones for bovine brain 2',3'-cyclic-nucleotide 3'-phosphohydrolase (CNPase, EC 3.1.4.37), the third most abundant protein in central nervous system myelin. The cDNA encodes the complete protein (400 amino acids) and hybridizes to a major size species of mRNA in bovine brain tissue, approx. 2.7 kb in size. CNPase mRNA levels do not appear to be affected in quaking dysmyelinating mutant mice. The sequence reveals probable sites for CNPase phosphorylation by cAMP-dependent protein kinase and a region of homology with haemocyanin.
