part of protein-containing complex ciliary transition zone MKS complex tectonic complex cellular_component GO:0036038 Although there is some evidence, it is still unclear if the MKS and NPHP complexes are constituents parts of the Y-shaped links or are simply responsible for aligning and attaching the Y-shaped links to the membrane and axoneme. bf tectonic-like complex 2011-11-22T11:21:28Z MKS module B9 complex 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.
