Predicted to enable dynein heavy chain binding activity and dynein light chain binding activity. Predicted to be involved in microtubule-based movement. Predicted to be located in sperm flagellum. Predicted to be part of cytoplasmic dynein complex. Orthologous to human DYNC1I1 (dynein cytoplasmic 1 intermediate chain 1) and DYNC1I2 (dynein cytoplasmic 1 intermediate chain 2).
