Dynein regulatory complex subunit 4 (GAS8)

Part of the nexin-dynein regulatory complex (N- DRC), a key regulator of ciliary/flagellar motility which maintains the integrity and alignment of the distal axoneme and modulates microtubule sliding in motile axonemes. Plays an essential part in the assembly of the N-DRC linker (By similarity).

Plays dual roles at both the primary (or non-motile) cilia to modulate hedgehog signaling and in motile cilia to coordinate cilia movement. Required for proper motile cilia functioning (PubMed:26387594, PubMed:27120127, PubMed:27472056).
