cDNA sequence and protein bioinformatics analyses of MSTN in African catfish (Clarias gariepinus).

Myostatin, also known as growth differentiation factor 8, has been identified as a potent negative regulator of skeletal muscle growth. The purpose of this study was to characterize and predict function of the myostatin gene of the African catfish (Cg-MSTN). Expression of Cg-MSTN was determined at three growth stages to establish the relationship between the levels of MSTN transcript and skeletal muscle growth.

cDNA structure and the effect of fasting on myostatin expression in walking catfish (Clarias macrocephalus, Günther 1864).

We cloned and sequenced the myostatin (MSTN) gene of walking catfish and characterized its expression under different conditions. The full cDNA sequence of MSTN was 1,784 bp, containing an open reading frame of 1,191 bp, which encoded 396 amino acids. The deduced MSTN sequence contained functional sites similar to other members of TGF-β superfamily, including the proteolytic processing site and nine conserved cysteines in the C-terminal.
