Participes in the structural integrity of both centrioles and basal bodies and in centriole cohesion (PubMed:19948479). Participates in the later stages of centriole assembly through the interaction with Rcd4 leading to the centriole to centrosome conversion (PubMed:32543652). Interacts with Rcd4;this complex is recruited to daughter centrioles before their conversion to centrosomes. Associated with the daughter centriole on mitotic entry (PubMed:32543652). Ana3 recruitment to the procentriole in interphase precedes the Rcd4 one (PubMed:32543652). Localizes to the basal bodies (PubMed:19948479). Belongs to the rotatin family.
