Microtubule inner protein (MIP) part of the dynein-decorated doublet microtubules (DMTs) in cilia axoneme, which is required for motile cilia beating . May play a role in the beating of primary cilia and thereby be involved in the establishment of organ laterality during embryogenesis .
Subcellular locations: Cytoplasm, Cytoskeleton, Cilium axoneme
Expressed in skin fibroblasts (at protein level). Expressed in airway epithelial cells .
