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). Light intermediate chain of the cytoplasmic dynein complex 2, a multisubunit complex composed at least of eleven different proteins. The cytoplasmic dynein 2 complex consists of two catalytic heavy chains (HCs) and a number of non-catalytic subunits presented by intermediate chains (ICs), light intermediate chains (LICs) and light chains (LCs). Among them, a heavy chain (DYNC2H1), two intermediate chains (DYNC2I2 and DYNC2I1), a light intermediate chain (DYNC2LI1), and a light chain (DYNLT2B) are unique to the dynein-2 complex, but a subset of light chains are also shared by dynein-1 and dynein-2 complexes (PubMed:31451806, PubMed:29742051). Dynein-2 complex is built around two copies of cytoplasmic dynein 2 heavy chain 1 (DYNC2H1). The C-terminal region of DYNC2H1 forms the motor domain, which converts the energy from ATP hydrolysis into movement. Its N-terminal region forms the tail, an extended structure that binds the other subunits and holds the two heavy chains in a homodimer. Interacts with DYNC2H1 (via N-terminus); this interaction stabilizes the dynein-2 complex structure (PubMed:29742051). Localizes to the apical cytoplasm. Expressed in bone, brain, kidney, and cartilage (PubMed:26077881, PubMed:26130459). Lower expression in heart, liver, lung, placenta and thymus (PubMed:26077881). The disease is caused by variants affecting the gene represented in this entry. Belongs to the dynein light intermediate chain family.
