Expression and functional characterization of vitronectin gene from Japanese flounder (Paralichthys olivaceus).


PMID 28377270

Abstract

Vitronectin (Vtn) is a multifunctional protein that plays significant roles in cell adhesion, migration, spreading and survival, and in the regulation of membrane attack complex formation and the terminal pathway of complement activation in innate immune response. However, the expression and immune significance of Vtn in fish remains largely unknown. In order to understand the involvement of Vtn in fish innate immune response, here we cloned and characterized a full-length Vtn ortholog cDNA, termed PoVtn, from Japanese flounder Paralichthys olivaceus. The deduced PoVtn protein is comprised of 438 amino acids with a 19-amino-acid signal peptide sequence (
