**Background of HAPLN4 Recombinant Protein**
HAPLN4 (Hyaluronan and Proteoglycan Link Protein 4) is a member of the link protein family, which stabilizes interactions between hyaluronan (HA) and proteoglycans in the extracellular matrix (ECM). These interactions are critical for maintaining the structural integrity and hydration of tissues, particularly in cartilage and the nervous system. HAPLN4 is closely associated with versican, a large chondroitin sulfate proteoglycan, and plays a role in organizing ECM networks essential for cell adhesion, migration, and signaling.
The recombinant form of HAPLN4 is produced using biotechnological methods, often in mammalian or bacterial expression systems, to ensure proper folding and post-translational modifications. This engineered protein retains the functional domains required for binding HA and proteoglycans, making it a valuable tool for studying ECM dynamics. Research has implicated HAPLN4 in tissue development, homeostasis, and pathologies such as osteoarthritis, cancer metastasis, and neurological disorders. Its dysregulation may contribute to ECM disorganization, affecting tissue resilience and cellular behavior.
Recent studies explore HAPLN4's therapeutic potential, including its use in regenerative medicine to repair damaged cartilage or neural tissues. Additionally, recombinant HAPLN4 serves as a reagent in biochemical assays to investigate HA-ECM interactions or screen for modulators of matrix assembly. Despite progress, detailed mechanistic insights into HAPLN4-specific functions remain limited, prompting ongoing research to elucidate its roles in health and disease.
In summary, HAPLN4 recombinant protein bridges fundamental ECM biology and translational applications, offering opportunities to address ECM-related disorders through targeted molecular strategies.
