| 摘 要： | Physico-chemical properties of FGF8 in Ctenopharyngodon idellus were analyzed by bioinformatics. The full - length grass carp FGF8 pro-polypeptide of 210 amino acids including 40 basic amino acids and 16 acidic amino acids. The signal peptide sequence is MRLIPSRLSYLFLHLFAFCYYA, and its cleavage site is located between Ala22 and Gln23. Grass carp FGF8 protein is a secreted protein since the typical character of secreted protein is that its N-domain contains a signal peptide. There are two N-glycosylation in the sites of Asn37 and Asn136, respectively, which were Asn-Phe-Thr and Asn-Tyr-Thr. The molecular weight （Mw） of grass carp FGF8 protein is 24.68 kDa. Its isoelectnic point （pl） is 10.93. The protein contains four main secondary structures： α-helix, β- sheet, β-turn and random coil.
