Cilia are slender, hair-like projections on the surface of many eukaryotic cells. They are classified as either motile or non-motile (primary cilia) and play critical roles in cell locomotion, fluid movement, sensing environmental cues, and signal transduction. The core structural component of a cilium is the axoneme, which typically consists of a ring of nine outer microtubule doublets surrounding a central pair of microtubules, known as the "9+2" arrangement in motile cilia. Primary cilia usually lack the central pair, resulting in a "9+0" structure.

Ciliary microtubules are stabilized and supported by various proteins, including inner arm dyneins, radial spokes, and nexin links, as well as numerous microtubule-associated proteins (MAPs). These components are essential for the proper assembly and function of the axoneme. Defects in the proteins associated with the ciliary microtubules can result in ciliopathies, a group of disorders that include diseases such as polycystic kidney disease, Bardet-Biedl syndrome, and primary ciliary dyskinesia.The term "inner protein" implies a location within the ciliary structure, potentially interacting directly with the microtubules to influence their stability, organization, or dynamic properties.
