Required for ciliogenesis and sonic hedgehog/SHH signaling. Required for the centrosomal recruitment of RAB8A and for the targeting of centriole satellite proteins to centrosomes such as of PCM1. May play a role in early ciliogenesis in the disappearance of centriolar satellites that preceeds ciliary vesicle formation . Involved in regulation of cell intracellular organization. Involved in regulation of cell polarity (By similarity). Required for asymmetrical localization of CEP120 to daughter centrioles (By similarity).
Subcellular locations: Cytoplasm, Cytoskeleton, Microtubule organizing center, Centrosome, Photoreceptor inner segment, Cytoplasm, Cytoskeleton, Microtubule organizing center, Centrosome, Centriole, Cytoplasm, Cytoskeleton, Cilium basal body
Forms a ring-like structure at the extreme distal end of both mother and daughter centrioles . In photoreceptor cells localized to the joint between the inner and outer segments, specifically localized at the mother centriole (basal body) and the adjacent centriole as well as between the two centrioles but not in the connecting cilium .
Ubiquitously expressed . Expressed in photoreceptor cells (at protein level) .
