Molecular cloning and expression of human neurochondrin-1 and -2

Human neurochondrins have been cloned from a brain cDNA library. The human neurochondrin-1 and -2 predict leucine-rich (15.8 and 15.9%) proteins of 729 and 712 amino acid residues, with molecular weights of 78.9 and 77.2 kDa, respectively. The deduced amino acid sequence indicates 98% identity among human, mouse and rat species. Northern analysis indicates that about 4 kb human neurochondrin mRNAs are abundant in the fetal and the adult brain.
