**Background of PLOD2 Recombinant Protein**
PLOD2 (procollagen-lysine, 2-oxoglutarate 5-dioxygenase 2), also known as lysyl hydroxylase 2 (LH2), is an enzyme encoded by the *PLOD2* gene in humans. It belongs to the PLOD family of iron- and 2-oxoglutarate-dependent dioxygenases, which play critical roles in post-translational collagen modification. Specifically, PLOD2 catalyzes the hydroxylation of lysine residues within collagen telopeptides, a step essential for the formation of stable collagen cross-links. This enzymatic activity ensures the proper maturation, stability, and mechanical strength of collagen fibrils in connective tissues.
PLOD2 is predominantly expressed in tissues rich in collagen, such as skin, bone, tendons, and blood vessels. Dysregulation of PLOD2 has been linked to pathological conditions, including fibrosis, cancer metastasis, and connective tissue disorders. For instance, its overexpression in fibrotic diseases promotes excessive collagen cross-linking, leading to tissue stiffening and organ dysfunction. In cancer, elevated PLOD2 levels enhance extracellular matrix (ECM) remodeling, facilitating tumor invasion and metastasis. Additionally, mutations in *PLOD2* cause rare genetic disorders like Bruck syndrome, characterized by brittle bones and joint contractures.
Recombinant PLOD2 protein is produced using expression systems (e.g., mammalian or insect cells) to ensure proper folding and enzymatic activity. It serves as a vital tool for studying collagen biochemistry, screening inhibitors for fibrosis or cancer therapy, and modeling diseases *in vitro*. Researchers also leverage recombinant PLOD2 to explore its interactions with ECM components or signaling pathways, offering insights into tissue repair and regenerative medicine strategies.
In summary, PLOD2 is a key regulator of collagen maturation with significant implications in both physiology and disease, making its recombinant form a valuable resource for biomedical research and therapeutic development.
