Required during ciliogenesis for tubulin glutamylation in cilium. Probably acts by participating in the transport of TTLL6, a tubulin polyglutamylase, between the basal body and the cilium. Found in a complex with TTLL6. Localizes mainly to the cilium basal body and in primary cilia. Expressed in testis and fetal tissues. Expressed in testis and fetal tissues. Although it contains a rhodanese domain, does not display phosphatase activity, suggesting that the protein is enzymatically inactive. The disease is caused by variants affecting the gene represented in this entry. Genetic variations in CEP41 may be associated with susceptibility to autism (PubMed:21438139). Belongs to the CEP41 family. Probable cloning artifact.
