TPC2 / TRP channels
Name: Two pore calcium channel protein 2
(TPC2)
Official Symbol: TPCN2
provided by HGNC
Function:
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.
