This gene encodes a 42.3 kD subunit of dynactin, a macromolecular complex consisting of 10 subunits ranging in size from 22 to 150 kD. Dynactin binds to both microtubules and cytoplasmic dynein. It is involved in a diverse array of cellular functions, including ER-to-Golgi transport, the centripetal movement of lysosomes and endosomes, spindle formation, chromosome movement, nuclear positioning, and axonogenesis. This subunit, like ACTR1A, is an actin-related protein. These two proteins are of equal length and share 90% amino acid identity. They are present in a constant ratio of approximately 1:15 in the dynactin complex.

Description
Specificity: Not tested with other proteins Relevance: In addition to conventional actins, there are several actin-related proteins. The ACTR1B protein and the ACTR1A protein are of equal length, and they share 90% amino acid identity and 96% amino acid similarity. ACTR1B is expressed in the cytosol as part of the dynactin complex. The dynactin complex has been shown to localize to multiple structures within the cell, including membrane organelles, the centrosome, spindle poles, and spindle pole microtubules during mitosis and prometaphase kinetochores. It regulates dyneinmediated vesicle movement on microtubules as well as spindle assembly and cell division. ACTR1B appears to be ivolved in dynein-driven vesicle movement.
