Protein description |
Native α-actinin from smooth muscle has a molecular mass of 200kDa, since it exists as a homodimer of 2x100kDa. Alpha-Actinins belong to the spectrin superfamily and are divided in four isoforms, encoded by different genes. Isoform 2 and 3 – the so called "muscle" α-actinins are constituents of sarcomeres in the cross-striated skeletal and cardiac muscle. Isoform 1 and 4 are "non-muscle" α-actinins and present in practically every tissue. |
|
Actin interaction |
Actin cross linking protein. Kd actin-binding = 1-5µM. |
