Part of a complex with bicd-1 and dlc-1, which is recruited to the nuclear envelope by unc-83, where in turn, it recruits dynein to the nuclear surface and regulates nuclear migration in hypodermal precursor cells. Component of a dynein-regulating complex composed of at least bicd-1, dlc-1 and egal-1. Probably recruited to the nuclear envelope by unc-83. RNAi-mediated knockdown results in animals that are viable. However, animals display a small, but significant, defect in nuclear migrations in hyp7 hypodermal precursor cells where an average of 3%, and up to 21% in a single animal, of nuclei fail to migrate.
