| Type: | Family | Name: | B9 domain |
| Description: | B9 domain containing proteins are found in flagellar or cilia-containing species. Although its function is unknown, a cilia-specific role has beensuggested for the poorly characterised B9 domain [, , ].Some proteins known to contain a B9 domain are listed below: Mammalian Meckel syndrome 1 (MKS1) protein, which may be related to the ciliary basal body. Mammalian protein B9D1 and B9D2. Caenorhabditis elegans X-box promoter element regulated protein 7 (xbx-7). It corresponds to mammalian MKS1. Caenorhabditis elegans ciliary transition zone associate protein 1 (tza-1). It corresponds to mammalian B9D2. Caenorhabditis elegans ciliary transition zone associate protein 2 (tza-2). It corresponds to mammalian B9D1. Paramecium tetraurelia ICIS-1 (Involved in Cilia Stability-1), the B9D2 homolog. | Short Name: | B9_dom |
