Dynein intermediate chain 1, axonemal; Part of the dynein complex of respiratory cilia.

Coiled-coil domain-containing protein 114; Probable component of the outer dynein arm complex required along the entire axoneme for tethering of outer dynein arms. Belongs to the ODA1/DCC2 family.

Dynein heavy chain 5, axonemal; Force generating protein of respiratory cilia. Produces force towards the minus ends of microtubules. Dynein has ATPase activity; the force-producing power stroke is thought to occur on release of ADP. Required for structural and functional integrity of the cilia of ependymal cells lining the brain ventricles. Belongs to the dynein heavy chain 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. 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.

Protein tilB homolog; May play a role in dynein arm assembly, hence essential for proper axoneme building for cilia motility; Belongs to the tilB family.

Dynein regulatory complex protein 1; 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. 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 CCDC65/DRC2 to form a central scaffold needed for assembly of the N-DRC and its attachment to the outer doublet microtubules; Belongs to the DRC1 family.

Dynein assembly factor 3, axonemal; Required for the assembly of axonemal inner and outer dynein arms. Involved in preassembly of dyneins into complexes before their transport into cilia (By similarity); Belongs to the DNAAF3 family.

Thioredoxin domain-containing protein 3; Probably required during the final stages of sperm tail maturation in the testis and/or epididymis, where extensive disulfide bonding of fibrous sheath (FS) proteins occurs. May be involved in the reduction of disulfide bonds within the sperm FS components. In vitro, it has neither NDP kinase nor reducing activity on disulfide bonds (By similarity).

Dynein assembly factor 1, axonemal; Cilium-specific protein required for the stability of the ciliary architecture. Plays a role in cytoplasmic preassembly of dynein arms (By similarity). Involved in regulation of microtubule-based cilia and actin-based brush border microvilli (By similarity); Belongs to the DNAAF1 family.
