Function

Required for ciliogenesis and sonic hedgehog/SHH sig ling. Role in primary cilia formation and microtubule organisation (19144723). Component of a CP110-containing protein complex required for centrosome and cilia function, 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. Essential for centrosomal migration prior to ciliogenesis (24421332). Mutated in Joubert syndrome (26096313) and in skeletal ciliopathies (31816441, 32080096) KIAA0586 … is essential for primary ciliogenesis. In control cells … protrude from 60% of cells … only 20% of mutant cells bear a primary cilia. (26166481)
