Protein: Polycystin-1 (Autosomal dominant polycystic kidney disease 1 protein homolog) (O08852)
Organism: Mus musculus (Mouse)
Function: Component of a heteromeric calcium-permeable ion channel formed by PKD1 and PKD2 that is activated by interaction between PKD1 and a Wnt family member, such as WNT3A and WNT9B. Both PKD1 and PKD2 are required for channel activity (By similarity). Involved in renal tubulogenesis. Involved in fluid-flow mechanosensation by the primary cilium in renal epithelium. Acts as a regulator of cilium length, together with PKD2. The dynamic control of cilium length is essential in the regulation of mechanotransductive signaling. The cilium length response creates a negative feedback loop whereby fluid shear-mediated deflection of the primary cilium, which decreases intracellular cAMP, leads to cilium shortening and thus decreases flow-induced signaling. May be an ion-channel regulator. Involved in adhesive protein-protein and protein-carbohydrate.
Subcellular location: Cell membrane {ECO:0000250|UniProtKB:P98161}; Multi-pass membrane protein {ECO:0000250|UniProtKB:P98161}. Cell projection, cilium {ECO:0000269|PubMed:12514735, ECO:0000269|PubMed:24939912, ECO:0000269|PubMed:25405894}. Endoplasmic reticulum {ECO:0000269|PubMed:25405894}. Golgi apparatus {ECO:0000269|PubMed:25405894}. Vesicle {ECO:0000250|UniProtKB:P98161}. Secreted, extracellular exosome {ECO:0000250|UniProtKB:P98161}. Note=PKD1 localization to the plasma and ciliary membranes requires PKD2, is independent of PKD2 channel activity, and involves stimulation of PKD1 autocatalytic cleavage at the GPS region of the GAIN-B domain (PubMed:12514735, PubMed:25405894). PKD1:PKD2 interaction is required to reach the Golgi apparatus from endoplasmic reticulum and then traffic to the cilia (PubMed:25405894). Ciliary localization of PKD1 requires BBS1 and ARL6/BBS3 (PubMed:24939912). Cell surface localization requires GANAB (By similarity). Detected on migrasomes and on extracellular exosomes in urine (By similarity). {ECO:0000250|UniProtKB:P98161, ECO:0000269|PubMed:12514735, ECO:0000269|PubMed:24939912, ECO:0000269|PubMed:25405894}.
