Beta-centractin is a protein that in humans is encoded by the ACTR1B gene .[5] [6] [7]
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.[7]
