The function of ENSG00000157856 (DRC1, dynein regulatory complex subunit 1) is as follows. 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 (PubMed:23354437, PubMed:34169321). Coassembles with DRC2 to form a central scaffold needed for assembly of the N-DRC and its attachment to the outer doublet microtubules (PubMed:23354437). {ECO:0000250|UniProtKB:P0DL09, ECO:0000269|PubMed:23354437, ECO:0000269|PubMed:34169321}.
