Involved in the biogenesis of cilia (By similarity). Required for the recruitment of PLK1 to centrosomes and S phase progression (By similarity). Homooligomer; probably required for localization to centrosomes (By similarity). Forms a complex with KIAA0753/OFIP and OFD1; within this complex may stabilize the interaction between OFD1 and KIAA0753/OFIP (PubMed:26643951). Interacts with PCM1; this interaction may be mediated by KIAA0753/OFIP (PubMed:26643951). Localization to centrioles and pericentriolar satellites may be mediated by KIAA0753/OFIP. Belongs to the CEP43 family.
