Cloning of Rat Calcium-Modulating Cyclophilin Ligand

Abstract

Rat calcium-modulating cyclophilin ligand (CAML) cDNA was cloned and sequenced. It has a predicted open reading frame of 294 amino acids. The CAML gene is highly conserved throughout species, showing 85, 89 and 69% amino acid sequence identity to the human, mouse, and chicken genes, respectively. Gene expression data using astrocytes, microglia and neurons show that CAML mRNA and protein is constitu-tively expressed in these cell types of the central nervous system. The cloning of rat CAML will facilitate further investigations on the function of this molecule.
