Background: beta-Actin

Actin is a highly conserved protein involved in cell motility, structure, and integrity. Six functional actin isoforms exist and were named based on their electrophoretic mobility and distribution including alpha-cardiac muscle actin (aCAA), alpha-skeletal muscle actin (aSKA), alpha-smooth muscle actin (aSMA), beta-cytoplasmic actin (bCYA), gamma-cytoplasmic actin (gCYA) and gamma-smooth muscle actin (gSMA) (1). The cytoplasmic isoforms, beta-actin and gamma-actin, are nearly identical, differing by only 4 amino acids at the N-terminus with a theoretical molecular weight of 42 kDa (2). Beta-actin is ubiquitously expressed in eukaryotic cells and considered a housekeeping gene which is frequently used as a loading control for assays involving protein detection, such as Western blotting (3,4).
