DYNC2I1 Gene

Name dynein 2 intermediate chain 1
Description This gene encodes a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD) and may facilitate the formation of heterotrimeric or multiprotein complexes. Members of this family are involved in a variety of cellular processes including cell cycle progression, signal transduction, apoptosis, and gene regulation. The encoded protein contains four WD repeats and may play a role in the formation of cilia. Mutations in this gene have been associated with short-rib polydactyly and Jeune syndromes.

Summary
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\n DYNC2LI1 (cytoplasmic dynein‐2 light intermediate chain 1) is an essential component of the dynein‐2 motor complex that drives retrograde intraflagellar transport (IFT) in primary cilia. It interacts directly with the dynein‐2 heavy chain (DYNC2H1) to stabilize the motor complex and ensure efficient trafficking of IFT particles along the axoneme. Functional studies in patient fibroblasts and model systems have shown that reduced DYNC2LI1 levels or pathogenic mutations lead to abnormal ciliary morphology—including altered cilia length, broadened tips, and even hyperelongation—as well as to the accumulation of IFT proteins within the cilium. Such defects impair key signaling pathways such as Hedgehog and ultimately disrupt normal skeletogenesis, as observed in skeletal ciliopathies (1,2,3). \n "}]}, {"type": "t", "text": "\n "}, {"type": "p", "children": [{"type": "t", "text": "\n These findings emphasize that DYNC2LI1 is not only critical for maintaining dynein‐2 complex integrity and retrograde ciliary trafficking but also for the proper function of ciliary signaling mechanisms that are essential for human development."}]}, {"type": "t", "text": "\n "}, {"type": "p", "children": [{"type": "fg", "children": [{"type": "fg_fs", "start_ref": "1", "end_ref": "3"}]}, {"type": "t", "text": ""}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "S Paige Taylor, Tiago J Dantas, Ivan Duran, et al.
