Function
Interacts with and ubiquitylates AZI1 and PCM1, regulates the composition and function of centriolar satellites and suppresses primary ciliogenesis (24121310). MIB1 destabilizes Talpid3 through poly- ubiquitylation and suppresses cilium assembly (27146717). It redistributes to centrioles in response to conditions that induce centriole amplification, interacts with Plk4 and promotes its ubiquitylation, which is important for centriole homeostasis (25795303).
