Polycystin-1 (PKD1)

Part of a heteromeric calcium-permeable ion channel formed by PKD1 and PKD2 that's triggered by interaction between PKD1 and a Wnt family member, such as WNT3A and WNT9B (PubMed:27214281). The two PKD1 and PKD2 are necessary for channel activity (PubMed:27214281).

Involved in renal tubulogenesis (PubMed:12482949). Involved in fluid-flow mechanosensation from the primary cilium in renal epithelium (By similarity).
