DCTN2

A gene on chromosome 12q13.3 that encodes dynactin-2 (a 50-kD subunit of dynactin), a macromolecular complex that binds to both microtubules and cytoplasmic dynein and effects an array of motor activities, including ER-to-Golgi transport, centripetal movement of lysosomes and endosomes, spindle formation, chromosome movement, nuclear positioning and axonogenesis. Dynactin-2 modulates cytoplasmic dynein binding to organelles, and plays a role in prometaphase chromosome alignment and spindle organisation during mitosis, anchoring microtubules to centrosomes. It may play a role in synapse formation during brain development.

For example, proteins involved in neuronal development [e.g., DPYL2, DPYL3, DPYL4, dynactin subunit 2 (DCTN2)] and synaptogenesis (DCTN2) were up-regulated.
