TPCA-1 compound, inhibiting testis-specific serine/threonine protein kinase 3 for potential male sterile in Bombyx mori.

Background: Protein kinases are a type of transferase enzyme that catalyze the phosphorylation of protein substrates, including receptor proteins. Testis-specific serine/threonine kinases (TSSKs) are a highly conserved group of protein kinases found in various organisms. They play an essential role in male reproduction by influencing sperm development and function.
