In Drosophila, the novel phosphorylated kinase CG9222 plays a crucial role during spermatogenesis. It regulates sperm development and maturation through specific phosphorylation events, affecting cell division, differentiation, and the formation of sperm structures like flagella. This kinase likely interacts with other proteins in a signaling cascade, modulating cellular processes such as gene expression, protein synthesis, or cytoskeletal dynamics. Its activity ensures proper sperm function and male fertility.
