The function of DYNC2LI1 (dynein cytoplasmic 2 light intermediate chain 1, ENSG00000138036) is as follows. Acts as one of several non-catalytic accessory components of the cytoplasmic dynein 2 complex (dynein-2 complex), a motor protein complex that drives the movement of cargos along microtubules within cilia and flagella in concert with the intraflagellar transport (IFT) system, facilitating the assembly of these organelles (PubMed:29742051). Involved in the regulation of ciliary length (PubMed:26077881, PubMed:26130459). {ECO:0000269|PubMed:26077881, ECO:0000269|PubMed:26130459, ECO:0000269|PubMed:29742051}.
