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