PRSS56. a member of the trypsin-like serine protease family, is a secreted enzyme encoded by the *PRSS56* gene. It plays a critical role in ocular development, particularly in regulating axial eye growth and maintaining proper lens and retinal architecture. Mutations in *PRSS56* are linked to autosomal recessive disorders such as posterior microphthalmia (MCOP2) and severe childhood-onset myopia, highlighting its importance in eye morphogenesis. The protein is thought to influence extracellular matrix remodeling and signaling pathways during eye development, though its precise substrates and molecular mechanisms remain under investigation.
Recombinant PRSS56 protein is produced using biotechnological platforms, such as mammalian or insect cell expression systems, to ensure proper post-translational modifications and functional activity. Researchers utilize this recombinant form to study PRSS56's enzymatic properties, substrate specificity, and interactions with other proteins in vitro. Its applications extend to disease modeling, particularly in understanding pathological eye elongation and refractive errors. By analyzing recombinant PRSS56 in cell-based assays or animal models, scientists aim to uncover its role in myopia development and test potential therapeutic interventions targeting its activity.
Additionally, recombinant PRSS56 serves as a tool for diagnostic development. Mutations in *PRSS56* are screened using protein structure-function analyses, aiding genetic counseling for families with inherited eye disorders. Recent studies also explore its involvement beyond ophthalmology, including potential roles in cancer progression due to protease-mediated tissue remodeling. Despite progress, challenges persist in characterizing its endogenous inhibitors and tissue-specific regulation. Ongoing research on recombinant PRSS56 continues to bridge gaps in ocular biology and translational medicine, offering insights into personalized treatments for vision-related diseases.
