Predicted to enable identical protein binding activity and protein C-terminus binding activity. Predicted to be involved in several processes, including intracellular transport of viral protein in host cell; neuron projection development; and positive regulation of Rac protein signal transduction. Predicted to be located in several cellular components, including axonal growth cone; cytoplasmic microtubule; and lamellipodium. Predicted to be part of cytoplasmic dynein complex. Orthologous to human DYNLT1 (dynein light chain Tctex-type 1). [provided by Alliance of Genome Resources, Apr 2022]
