Recombinant human DPY19L2 protein is derived from the DPY19L2 gene, located on chromosome 19 (19q13.12). This gene encodes a transmembrane protein predominantly expressed in the testis and implicated in sperm head formation and acrosome development during spermatogenesis. DPY19L2 functions as a putative glycosyltransferase, potentially involved in membrane structure organization or protein glycosylation. Mutations in DPY19L2 are strongly associated with globozoospermia, a rare male infertility disorder characterized by round-headed sperm lacking acrosomes, rendering them incapable of fertilization. Researchers produce recombinant DPY19L2 using expression systems like E. coli or mammalian cells, enabling studies on its biochemical properties, structural interactions, and role in spermatogenesis. This protein is critical for developing diagnostic tools for genetic infertility screening and exploring therapeutic strategies, such as correcting acrosomal defects. Additionally, recombinant DPY19L2 aids in generating antibodies for research or clinical assays. Despite progress, its precise enzymatic activity and molecular targets during acrosome biogenesis remain under investigation, highlighting the need for further functional studies.
