Non-selective calcium permeant cation channel (PubMed:12077604, PubMed:12077606, PubMed:26818531, PubMed:37648856, PubMed:38691614). It is activated by innocuous (warm) temperatures and shows an increased response at noxious temperatures greater than 39 degrees Celsius (PubMed:12077604, PubMed:12077606). Activation exhibits an outward rectification (PubMed:12077604). The channel pore can dilate to provide permeability to larger cations (PubMed:37648856). May associate with TRPV1 and may modulate its activity (PubMed:12077606). Is a negative regulator of hair growth and cycling: TRPV3-coupled signaling suppresses keratinocyte proliferation in hair follicles and induces apoptosis and premature hair follicle regression (catagen) (PubMed:21593771). {ECO:0000269|PubMed:12077604, ECO:0000269|PubMed:12077606, ECO:0000269|PubMed:21593771, ECO:0000269|PubMed:26818531, ECO:0000269|PubMed:37648856, ECO:0000269|PubMed:38691614}. This is the function of TRPV3 (transient receptor potential cation channel subfamily V member 3, Ensembl gene identifier ENSG00000167723).
