Acts as one of several non-catalytic accessory components of the cytoplasmic dynein 1 complex that are thought to be involved in linking dynein to cargos and to adapter proteins that regulate dynein function. Cytoplasmic dynein 1 acts as a motor for the intracellular retrograde motility of vesicles and organelles along microtubules. The intermediate chains mediate the binding of dynein to dynactin via its 150 kDa component (p150-glued) DCNT1. Involved in membrane-transport, such as Golgi apparatus, late endosomes and lysosomes.
Belongs to the dynein intermediate chain family. Contains 7 WD repeats.
Phosphorylated upon DNA damage, probably by ATM or ATR. The phosphorylation status of Ser-90 appears to be involved in dynactin-dependent target binding.
