General Information
Term MKS complex ID (Ontology) GO:0036038 (Gene Ontology)
Definition A protein complex that is located at the ciliary transition zone and consists of several proteins some of which are membrane bound. Acts as an organiser of transition zone inner structure, specifically the Y-shaped links, in conjunction with the NPHP complex. The MKS complex also acts as part of the selective barrier that prevents diffusion of proteins between the ciliary cytoplasm and cellular cytoplasm as well as between the ciliary membrane and plasma membrane.[ PubMed:21422230 PubMed:21565611 PubMed:21725307 PubMed:22179047 PubMed:25869670 PubMed:26595381 PubMed:26982032 ]
