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. Applications: Suitable for use in Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilution: Western Blot: 0.5-2ug/ml Immunohistochemistry (paraffin): 3-5ug/ml Optimal dilutions to be determined by the researcher.
