Acts as one of several non-catalytic accessory components of the cytoplasmic dynein 1 complex that are thought to be involved in linking dynein to cargos and to adapter proteins that regulate dynein function. Cytoplasmic dynein 1 acts as a motor for the intracellular retrograde motility of vesicles and organelles along microtubules. May be involved in some aspects of dynein-related intracellular transport and motility. May play a role in changing or maintaining the spatial distribution of cytoskeletal structures (By similarity). Homodimer. The cytoplasmic dynein 1 complex consists of two catalytic heavy chains (HCs) and a number of non-catalytic subunits which present intermediate chains (ICs), light intermediate chains (LICs) and light chains (LCs); the composition seems to vary in respect to the IC, LIC and LC composition. The heavy chain homodimer serves as a scaffold for the probable homodimeric assembly of the respective non-catalytic subunits. Dynein ICs and LICs bind directly to the HC dimer and the LCs assemble on the IC dimer. Interacts with DYNC1I1. Interacts with BMF. Component of the myosin V motor complex. Interacts with BCAS1. Interacts with Basson/BSN (By similarity). Interacts with Basson/BSN (By similarity). Interacts with AMBRA1 (via TQT motifs); tethering AMBRA1 to the cytoskeleton (By similarity). Belongs to the dynein light chain family.
