Cloning of a HcCreb gene and analysis of its effects on nacre color and melanin synthesis in Hyriopsis cumingii.

ABSTRACT: Creb (Cyclic AMP response element binding protein) is a nuclear regulatory factor that regulates transcription through autophosphorylation. In melanocytes, cAMP's corresponding elements bind to the Creb protein to autophosphorylation and activate MITF (Microphthalmia-associated transcription factor). MITF stimulates Tyrosine(tyr) to induce melanocytes to differentiate into eumelanin and pheomelanin. In this study, a HcCreb gene in Hyriopsis cumingii was cloned and its effects on melanin synthesis and nacre color were studied. HcCreb was expressed in both purple and white mussels, and there was a significant difference in expression between adductor muscle (p<0.01) and mantle tissue (p<0.05). Other tissues did not show significant differences (except for gill tissue), and in general, the le
