LEPREL1 (Leprecan Homolog 1), also known as Prolyl 3-Hydroxylase 2 (P3H2), is a member of the lysyl hydroxylase family that plays a critical role in collagen biosynthesis. This enzyme catalyzes the post-translational hydroxylation of specific proline and lysine residues in collagen chains, a modification essential for stabilizing collagen triple helices and ensuring proper extracellular matrix (ECM) assembly. LEPREL1 is particularly notable for its 3-hydroxylation activity on the Pro986 residue in the α1 chain of type I collagen, a key step in collagen maturation. Dysregulation of LEPREL1 has been implicated in connective tissue disorders, fibrosis, and cancer metastasis due to its influence on ECM integrity and cell signaling.
Recombinant LEPREL1 protein is engineered to study its enzymatic mechanisms and interactions. Typically produced in mammalian or insect cell systems to ensure proper folding and post-translational modifications, the recombinant protein retains hydroxylase activity and can be used in vitro to investigate collagen modification pathways. Researchers employ it to model diseases like osteogenesis imperfecta, where collagen hydroxylation defects are pathological hallmarks. Additionally, it serves as a tool for drug screening targeting collagen-related disorders or fibrosis. Structural studies using recombinant LEPREL1 have revealed insights into its substrate-binding domains and catalytic sites, distinguishing it from other isoforms like P3H1/P3H3. Despite its functional significance, LEPREL1's regulatory networks and tissue-specific roles remain partially unexplored, driving ongoing research to clarify its contributions to ECM dynamics and therapeutic potential.
