Polycystin-1 is a [[glycoprotein]] which contains a large N-terminal extracellular region, multiple [[transmembrane domain]]s and a cytoplasmic C-tail. It may function as an integral membrane protein involved in cell-cell/matrix interactions, and may modulate intracellular calcium homoeostasis and other [[signal transduction|signal-transduction]] pathways.

Polycystin 1 (often abbreviated to PC1) is a protein that in humans is encoded by the PKD1 gene [1][2]. Mutations of PKD1 are associated with most cases of autosomal dominant polycystic kidney disease, a severe hereditary disorder of the kidneys characterised by the development of renal cysts and severe kidney dysfunction [3].

Protein Structure and Function

File:PKD1PKD2 en.png
PC1 interacts with polycystin 2 via a cytoplasmic coiled-coil domain.

PC1 is a membrane-bound protein 4303 amino acids in length expressed largely upon the primary cilium, as well as apical membranes, adherens junctions, and desmosomes [4]. It possesses eleven transmembrane domains, a large extracellular N-terminal domain, and a short (~200 amino acid) cytoplasmic C-terminal domain [4][5]. This intracellular domain contains a coiled-coil domain through which PC1 interacts with polycystin 2 (PC2), a membrane-bound Ca2+-permeable ion channel.

PC1 has been proposed to act as a G protein–coupled receptor [4][6]. The C-terminal domain may be cleaved in a number of different ways. In one instance, a ~35 kDa portion of the tail has been found to accumulate in the cell nucleus in response to decreased fluid flow in the mouse kidney [7]. In another instance, a 15 kDa fragment may be yielded, interacting with transcriptional activator and co-activator STAT6 and p100, or components of the canonical Wnt signaling pathway in an inhibitory manner [8][9].

Evidence suggests that PC1 mediates mechanosensation of fluid flow by the primary cilium in the renal epithelium and of mechanical deformation of articular cartilage [10].

Gene

Splice variants encoding different isoforms have been noted for PKD1. The gene is closely linked to six pseudogenes in a known duplicated region on chromosome 16p.[11]
