The B9-C2 domain is found in proteins associated with the ciliary basal body. B9 domains were identified as a specific family of C2 domains. There are three sub-families represented by this family, notably, Mks1-Xbx7, Stumpy-Tza1 and Tza2 groups of proteins. Mutations in human Mks1 result in the developmental disorder Mechler-Gruber syndrome; mutations in mouse Stumpy lead to perinatal hydrocephalus and severe polycystic kidney disease. All the three distinct types of B9-C2 proteins cooperatively localise to the basal body or centrosome of cilia. Length = 165
>PF07162 B9-C2: Ciliary basal body-associated, B9 protein; InterPro: IPR010796 Proteins in this entry include the MSK1 protein (Q9NXB0 from SWISSPROT) and other known or predicted flagellar basal body proteome components [] or cilia-containing species
Although the function is unknown, a cilia-specific role has been suggested for the poorly characterised B9 domain [, , ]. Mutations in MSK1 have been shown to cause Meckel syndrome type 1, a severe foetal development disorder that has been reported in most populations.
