Dynein regulatory complex protein 1 (DRC1)

Part 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 modulates microtubule sliding in motile axonemes (By similarity). Plays a crucial role in the assembly of N-DRC and stabilizes the assembly of multiple inner dynein arms and radial spokes.

Coassembles with CCDC65/DRC2 to form a central scaffold required for assembly of the N-DRC and its attachment to the outer doublet microtubules (PubMed:23354437). .
