Protein BEX5; Brain expressed X-linked 5; Belongs to the BEX family.

Sentan; May be a component of the linker structure that bridges the ciliary membrane and peripheral singlet microtubules.

Leucine-rich repeat-containing protein 46; Leucine rich repeat containing 46.

Glutamate-rich protein 3; Glutamate rich 3.

Radial spoke head 14 homolog; Belongs to the flagellar radial spoke RSP14 family.

Translin-associated factor X-interacting protein 1; Possible role in spermatogenesis.

Cilia- and flagella-associated protein 161; May play a role in motile cilia function, possibly by acting on dynein arm assembly.

RNA polymerase II-associated protein 1; Forms an interface between the RNA polymerase II enzyme and chaperone/scaffolding protein, suggesting that it is required to connect RNA polymerase II to regulators of protein complex formation. Required for interaction of the RNA polymerase II complex with acetylated histone H3; Belongs to the RPAP1 family.

Dynein regulatory complex subunit 2; Component of the nexin-dynein regulatory complex (N-DRC), a key regulator of ciliary/flagellar motility which maintains the alignment and integrity of the distal axoneme and regulates microtubule sliding in motile axonemes (By similarity). Plays a critical role in the assembly of N-DRC and also stabilizes the assembly of multiple inner dynein arms and radial spokes. Coassembles with DRC1 to form a central scaffold needed for assembly of the N-DRC and its attachment to the outer doublet microtubules. Belongs to the DRC2 family.
