Beta-actin (gene name ACTB) is one of six different actin isoforms which have been identified in humans. This is one of the two nonmuscle cytoskeletal actins. Actins are highly conserved proteins that are involved in cell motility, structure and integrity. Alpha actins are a major constituent of the contractile apparatus.[1]



Beta-actin has been shown to interact with SPTBN2.[2][3]
