Enables several functions, including dynactin binding activity; dynein complex binding activity; and dynein light intermediate chain binding activity. Involved in several processes, including microtubule anchoring at microtubule organizing center; minus-end-directed organelle transport along microtubule; and retrograde vesicle-mediated transport, Golgi to endoplasmic reticulum. Acts upstream of or within microtubule-based movement. Located in Golgi apparatus and cytoplasmic vesicle. Is expressed in several structures, including central nervous system; dorsal root ganglion; olfactory epithelium; and retina. Human ortholog(s) of this gene implicated in spinal muscular atrophy with lower extremity predominance 2A and spinal muscular atrophy with lower extremity predominante 2B. Orthologous to human BICD2 (BICD cargo adaptor 2). [provided by Alliance of Genome Resources, Apr 2022]
