PIRT / TRP channels
Name: Phosphoinositide-interacting protein
(PIRT)
Official Symbol: PIRT
provided by HGNC
Function:
Regulatory subunit of TRPV1, a molecular sensor of noxious heat and capsaicin. Positively regulates TRPV1 channel activity via phosphatidylinositol 4,5-bisphosphate (PIP2). Binds various phosphoinositide, including phosphatidylinositol 4,5-bisphosphate (PIP2), but not phosphatidylinositol (PI) (By similarity).
