Résumé
A full-length complementary DNA encoding an actin was isolated from a Mytilus galloprovincialis hemocyte library. This actin displays a typical 376 amino acid open reading frame. Northern blotting indicated that the expression of the actin gene is particularly abundant in muscular tissues. This actin cDNA will be useful as a potential genetic marker as a standard for expression level in genetic regulation studies and will allow screening for the whole gene as well as its upstream regulation sequences.
