Molecular Cloning, Characterization, and Function of Insulin-Related Peptide 1 (IRP1) in the .

Abalone is a popular mollusk in the marine aquaculture industry of China. However, existing challenges, like slow growth, individual miniaturization, and the absence of abundant abalone, have emerged as significant obstacles impeding its long-term progress in aquaculture. Studies have demonstrated that insulin-related peptide ) is a crucial factor in the growth of marine organisms. However, limited studies have been conducted on in abalone. This study indicated that the hdh-MIRP1 open reading frame (ORF) was composed of 456 base pairs, which encoded 151 amino acids. Based on the gene expression and immunofluorescence analyses, the cerebral ganglion of () was the primary site of hdh-MIRP1 mRNA expression. Moreover, 1 expression was observed to be higher in the larger group than in the smaller group abalones. Only single nucleotide polymorphism (SNP) was related to their growth characteristics. However, approximately 82 proteins that may interact with 1 were identified. The functional enrichment analysis of the 82 genes indicated that 1 may be involved in the regulation of glucose metabolism and the process of growth. This study established a benchwork for further investigating the role of in the growth of abalone.
