May play a role in ciliogenesis (By similarity). In cooperation with CBY1 may facilitate ciliogenesis likely by the recruitment and fusion of endosomal vesicles at distal appendages during early stages of ciliogenesis (PubMed:27528616). Homodimer (via BAR-like domain) (PubMed:27528616). Heterodimer (via BAR-like domain) with FAM92A (PubMed:27528616). Interacts with CBY1 (PubMed:27528616). Extensive colocalization with CBY1 at mother centrioles. Restricted to certain tissues, most prominently expressed in multicilaited tissues. The BAR-like domain displays limited similarity to other BAR domains. Belongs to the CIBAR family.
