Secondary Information | |
| Protein Function | essential in cell division, migration, junction formation, chromatin remodeling, transcriptional regulation, vesicle trafficking, and cell shape regulation; Four isoforms, αskeletal-actin, αcardiac-actin, αsmooth-actin, and ɣ smooth-actin, are expressed primarily in skeletal, cardiac, and smooth muscle; two isoforms, bcyto-actin and ccyto-actin are ubiquitously expressed; maintenance of the cytoskeleton, cell motility and muscle contraction |
| Biochemical Properties | three components have different pIs; ratio of the three isoelectric species was calculated from a densitometric scan of the gel: α like 72%, ß-like 7%, and γ-like 21%; α like actin as the major smooth muscle actin in aorta tissue; both actin samples contained a small amount of the nonmuscle actins p and y with p expressed preferentially; actins from bovine and chicken aorta give an extremely similar ftngerprint pattern of their amino-terminal peptides labeled by C14-carboxymethylatio |
