Molecular cloning and sequence of gilthead sea bream (Sparus aurata) alpha-skeletal actin: tissue and developmental expression

Comp Biochem Physiol B Biochem Mol Biol. 2001 Aug;130(1):13-21. doi: 10.1016/s1096-4959(01)00381-5.


In the present study, the Sparus aurata alpha-skeletal actin was cloned from a mixed larvae complementary DNA library. The clone isolated was 1523 bp long with an open reading frame of 1134 bp coding for a 377-amino acid protein. The deduced amino acid sequence of sea bream alpha-actin is identical to Fugu alpha-actin-1. The expression of alpha-actin was initiated at the onset of segmentation. In adult fish, alpha-actin is expressed predominantly in white and red muscle.
