Prss28. also known as protease serine 28. is a member of the serine protease family, a class of enzymes characterized by a conserved catalytic triad (serine, histidine, and aspartic acid) essential for hydrolytic activity. Serine proteases play critical roles in diverse physiological processes, including blood coagulation, immune response, and tissue remodeling. Prss28 is encoded by the PRSS28 gene and is classified as a trypsin-like protease due to structural similarities with pancreatic trypsin, though its precise biological functions remain less defined compared to well-studied homologs.
This protein is synthesized as an inactive zymogen, requiring proteolytic cleavage for activation. It is expressed in specific tissues, with studies suggesting its presence in epithelial cells, immune-related tissues, and certain cancers. Emerging research links Prss28 to extracellular matrix (ECM) remodeling and cellular signaling pathways, potentially influencing inflammation, wound healing, and tumor progression. Its dysregulation has been observed in diseases such as psoriasis and colorectal cancer, implicating it as a biomarker or therapeutic target.
Recombinant Prss28 protein is produced using heterologous expression systems (e.g., mammalian, insect, or bacterial cells) to enable functional studies. Purification typically involves affinity chromatography tags (e.g., His-tag) and enzymatic activity validation using synthetic substrates. Researchers employ this tool to investigate substrate specificity, inhibitor screening, and mechanistic roles in disease models. Challenges include maintaining proper post-translational modifications (e.g., glycosylation) critical for native activity, often necessitating eukaryotic expression systems.
Current research focuses on elucidating Prss28's physiological substrates, regulatory mechanisms, and disease associations. Its potential as a diagnostic or therapeutic target drives interest in structural characterization and inhibitor development, aiming to modulate its activity in pathological conditions.
