AbstractBackground: To date, more than 300,000 distinct peptides have been identified in scorpion venom. However, only a limited number of these peptides have been described. Objectives: We characterized some putative peptides from the venom gland cDNA library of the Iranian yellow scorpion Hemiscorpius lepturus. Methods: Total RNA was extracted from yellow Iranian scorpion glands. Single-stranded cDNA (sscDNA) and double-stranded cDNA (dscDNA) were synthesized by polymerase chain reaction (PCR). A cDNA library was achieved by inserting dscDNA into a special vector and subsequently transformed to chemically competent Escherichia coli as a host. The library was screened by culturing the liquid library on Lysogeny broth (LB)-agar plates. Analysis of positive clones was performed by plasmid extraction and the sequencing of the inserts. Finally, all cDNA sequences were analyzed and characterized by bioinformatics software. Results: One hundred colonies were randomly analyzed. Eighty-nine cDNA sequences had acceptable quality for bioinformatics analysis. Five sequences were selected for further analysis. The peptides related to these sequences were divided into two groups, non-disulfide bridge peptides (NDBP) and disulfide bridge peptides (DBP), the application of which in health and medical issues has been suggested. Conclusions: The data obtained in this study may be an important resource for further in vivo and in vitro functional assays to identify valuable therapeutic peptides.en
