General description

Actin is a highly abundant and conserved protein. It can transition between the monomeric (G-actin) and filamentous (F-actin) forms, which is influenced by external factors. Actin is expressed in smooth, skeletal and cardiac muscles.

Application

Actin from bovine muscle has been used as an internal standard and positive control during western blotting.

Biochem/physiol Actions

Actin is involved in a wide variety of cellular processes like cell migration, phagocytosis, cell polarity and shape. It associates with myosin and aids in muscle contraction. The protein acts as a building block of microfilaments.

Physical form

Lyophilized powder containing Tris, ATP and CaCl2

Actin

Although actin is one of the most conserved eukaryotic proteins, it is expressed as six isoforms characterized by electrophoresis and amino acid sequence analysis. Four of the six isoforms represent differentiation markers of muscle tissues. The other two are found in practically all cells.
