This protein family is found in eukaryotes. The function of this protein is to aid the production of new cilia in ciliogenesis. Mutations in the protein cause a disease, named Joubert syndrome type 14 (JBTS14) and also affect cell signalling using the Wnt pathway[1]. Proteins in this family are typically between 203 and 512 amino acids in length. There are two completely conserved G residues that may be functionally important.

1: TMEM237 is mutated in individuals with a Joubert syndrome related disorder and expands the role of the TMEM family at the ciliary transition zone.
