Calcipressin-3 is a protein that in humans is encoded by the RCAN3 gene and is a member of the Calcipressin family of proteins.[5][6]
RCAN3 is highly expressed in the Cerebellar Hemisphere, Prostrate, and the Mucosa of the esophagus.[7]
RCAN3 was present in the common ancestor of all animals. As a result, orthologs are present in other species, including mice (Rcan3), chickens (RCAN3), and zebrafish (rcan3).[8]
Calcipressin-3, along with the other two Calcipressin proteins have been identified as possible contributing factors to Down Syndrome in humans.[9]
