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% aa identity and 96% aa 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.
