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). . This is the function of Ensembl gene identifier ENSG00000153789 (CIBAR2, CBY1 interacting BAR domain containing 2).
