**Background of OPTC Recombinant Protein**
Opticin (OPTC) is a small leucine-rich proteoglycan primarily expressed in the eye, notably within the vitreous humor and retinal tissues. It plays a critical role in maintaining ocular extracellular matrix (ECM) organization by regulating collagen fibril arrangement, ensuring vitreous transparency and structural stability. OPTC interacts with type II and XI collagens, modulating fibrillogenesis and preventing abnormal aggregation, which is vital for visual function. Genetic studies link the *OPTC* gene (located on human chromosome 1q25-q31) to ocular disorders like glaucoma and retinal degeneration, underscoring its physiological relevance.
Recombinant OPTC protein is produced using biotechnological platforms, such as *E. coli* or mammalian expression systems, enabling scalable synthesis for research and therapeutic applications. The protein is purified via affinity chromatography, retaining its functional domains for collagen-binding and ECM modulation. Its recombinant form has become a valuable tool for studying cell-ECM interactions, collagen dynamics, and disease mechanisms in vitro and in vivo.
In translational research, OPTC recombinant protein holds promise for treating vitreoretinopathies, glaucoma, and age-related vision loss. It is explored for ECM-targeted therapies, tissue engineering (e.g., synthetic vitreous substitutes), and drug delivery systems. Additionally, OPTC’s anti-angiogenic and anti-inflammatory properties are under investigation for broader ocular and non-ocular applications. By elucidating OPTC’s molecular roles and leveraging recombinant technology, researchers aim to develop novel strategies for restoring ECM homeostasis and addressing degenerative diseases.
