Involved in the planar cell polarity (PCP) pathway that is essential for the polarization of epithelial cells during morphogenetic processes, including gastrulation and neurulation (By similarity). PCP is maintained by two molecular modules, the global and the core modules, PRICKLE3 being part of the core module (By similarity). Distinct complexes of the core module segregate to opposite sides of the cell, where they interact with the opposite complex in the neighboring cell at or near the adherents junctions (By similarity). Involved in the organization of the basal body (By similarity). Involved in cilia growth and positioning (By similarity). Required for proper assembly, stability, and function of mitochondrial membrane ATP synthase (mitochondrial complex V) .
Cytoplasm . Cell membrane ; Peripheral membrane protein ; Cytoplasmic side . Mitochondrion . Recruited by VANGL2 to anterior cell borders. This polarity is controlled by Wnt proteins (By similarity). WTIP is involved in the recruitment of PRICKLE3 to the basal body (By similarity). .
Widely expressed.
