Dynein light chain Tctex-type 3 (DYNLT3)

Acts as one of many non-catalytic attachment components of the cytoplasmic dynein 1 complex that are thought to be involved in linking dynein to cargos and to adapter proteins which regulate dynein function. Cytoplasmic dynein 1 acts as a motor for the intracellular retrograde motility of vesicles and organelles along microtubules.

Probably binds BUB3 as part of transport cargo. Required for the efficient progression through mitosis (By similarity).
