Previous GeneCards Identifiers for TPCN2 Gene
This gene encodes a putative cation-selective ion channel with two repeats of a six-transmembrane-domain. The protein localizes to lysosomal membranes and enables nicotinic acid adenine dinucleotide phosphate (NAADP) -induced calcium ion release from lysosome-related stores. This ubiquitously expressed gene has elevated expression in liver and kidney. Two common nonsynonymous SNPs in this gene strongly associate with blond versus brown hair pigmentation.[provided by RefSeq, Dec 2009]

TPCN2 (Two Pore Segment Channel 2) is a Protein Coding gene. Diseases associated with TPCN2 include Deafness, Autosomal Recessive 63 and Deafness, Autosomal Recessive 7. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and Ion channel transport. GO annotations related to this gene include identical protein binding and ion channel activity. An important paralog of this gene is TPCN1.
UniProtKB/Swiss-Prot for TPCN2 Gene
Nicotinic acid adenine dinucleotide phosphate (NAADP) receptor that may function as one of the major voltage-gated Ca(2+) channels (VDCC) across the lysosomal membrane. May be involved in smooth muscle contraction.
