Investigating the Ancestral and Novel Functional Roles of Insl3: Gene Structure Parameters and Bioinformatics as Key Tools in Evolutionary Biology Research.

This study investigates insulin-like 3 (INSL3), also known as Leydig cell-specific insulin-like peptide (LEY I-L), within the framework of evolutionary biology. It examines key aspects of gene structure, such as dynamics and intronic phase, and employs bioinformatics tools to explore both the ancestral and modern functional roles of Insl3.
Insulin-like 3 (INSL3) belongs to a superfamily of peptides, growth factors, and hormones that includes insulin, IGF, and relaxin. INSL3 is primarily produced as a pre-prohormone in the somatic cells of the gonads, particularly in the Leydig cells of the testes and theca cells of ovarian follicles. cDNA sequences of INSL3 have been isolated from several vertebrate species. The structure of the INSL3 gene is similar to that of insulin and relaxin, consisting of two exons and one intron.
