General annotation (Comments)
| Function | Modulates cytoplasmic dynein binding to an organelle, and plays a role in prometaphase chromosome alignment and spindle organization during mitosis. Involved in anchoring microtubules to centrosomes. May play a role in synapse formation during brain development. |
| Subunit structure | Subunit of dynactin, a multiprotein complex associated with dynein. Interacts with BICD2 and CEP135 By similarity. Interacts with DYNAP, ECM29 and MAPRE1. Ref.9 Ref.13 Ref.14 |
| Subcellular location | Cytoplasm › cytoskeleton › centrosome. Membrane; Peripheral membrane protein Ref.1. |
| Sequence similarities | Belongs to the dynactin subunit 2 family. |
| Sequence caution | The sequence AAO34395.1 differs from that shown. Reason: Frameshift at position 381. |
