Microtubule inner protein (MIP) part of the dynein-decorated doublet microtubules (DMTs) in cilia axoneme (By similarity). Important for proper ciliary and flagellar beating. May act in cooperation with CFAP45 and axonemal dynein subunit DNAH11. May play a role in cell growth and/or survival (By similarity).
Subcellular locations: Cytoplasm, Cell projection, Cilium, Flagellum, Cytoplasm, Cytoskeleton, Cilium axoneme
Located in the proximal region of respiratory cilia.
