The function of ENSG00000100578 (KIAA0586, KIAA0586) is as follows. 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 (PubMed:24421332). 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). {ECO:0000250|UniProtKB:E9PV87, ECO:0000250|UniProtKB:Q1G7G9, ECO:0000269|PubMed:24421332}.
