bovine thyroid actin is very similar to actins from other tissues on the basis of : ( 1 ) comigration with rabbit skeletal muscle actin during gel electrophoresis in sodium dodecyl sulfate , ( 2 ) its amino acid composition , which includes about 1 mole of 3-methylhistidine per 42,000 g , ( 3 ) its ability to bind and inhibit pancreatic deoxyribonuclease i , and ( 4 ) its ability to form 7-8 nm microfilaments which is similar to that of skeletal filamentous actin .
