Abstract：In this study, we predict the secretory proteins of microsporidium Hepatospora eriocheir genome parasited in Chinese mitten crab Eriocheir sinensis with the EuSecPred 2.0 and annotate for secreted protein function, characteristics and the sequence analysis. The length of secreted proteins was found to be primarily changed from 30 amino acids to 300 amino acids, with length of signal peptide from 11 amino acids to 23 amino acids. The signal peptide cleavage site was mainly composed of hydrophobic amino acids. Many key proteins were found by functional annotation of the secretory proteins such as haemaglutinin-esterase, methyltransferase EZH1, and serine/threonine protein kinase. Motif analysis revealed that there was a S[NS]N[TI][FI]VI[IGD][RG]VRC motif in signal peptides which predicted secreted proteins were involved in the physiological activities of H. eriocheir, host cell cycle regulation and immune response. The findings provide important basis for screening disease-related candidate factors and exploring the infection mechanism.
