beta actin is a type of cell skeleton protein.Its gene is a house keeping gene.In most of cells,beta actin,such as human skeleton,is expressed in a certain level.THat is the reason that people use beta-actin as the criteria of cell numbers.But numerious experiments demonstrated that beta-actin expression is not constant as its previously described,such as under the circumistance of cell starvation and growth signal stimulation,beta-actin expression is either upregulated or downregulated.Therefore,if you use beta-actin as internal control in Western Blot,you have to think about these circumistance,as though beta-actin is the most popular protein sign to be as internal control.
