• Transition zone

Function

Also known as JBTS-14 . Interacts functionally with NPHP4, MKS2, MKSR1, MKSR2, and MKS5 at the transition zone. Its interaction with NPHP4 promotes basal body-TZ attachment to the membrane and cilium formation. Loss of TMEM237 results in defective ciliogenesis and deregulation of Wnt signaling. Mutated in Joubert syndrome related disorders (22152675).
