The transient receptor potential cation channel subfamily V member 6 (TRPV6): Genetics, biochemical properties, and functions of exceptional calcium channel proteins

Abstract

The transient receptor potential cation channel subfamily V member 6 (TRPV6) gene and cDNA were identified 15 years ago and exceptional observations on TrpV6 proteins and their function as a Ca2+-selective cation channel have been made since then. In this review we will summarize recent studies regarding the genetics, biochemical properties, and physiological functions of murine and human TrpV6 channel proteins. We will focus on TRPV6 gene polymorphisms, the start of TRPV6 translation at a non-AUG codon and the functions of TRPV6 in intestinal Ca2+ uptake, sperm maturation, and male fertility.
