Ready-to-use ELISA kits are available for the detection of C1orf89, an alias of the protein, ciliogenesis and planar polarity effector 2. The official gene symbol is CPLANE2. The protein, with a mass of 28.5 kDa and length of 258 residues, is reported to be cytoplasmic. It is a member of the Small GTPase superfamily, Rab family and may be known by other names, including: RSG1, miro domain-containing protein C1orf89, Rem/Rab-Similar GTPase 1, REM2- and Rab-like small GTPase 1, and REM2 and RAB like small GTPase 1.
