**Background of COL5A2 Recombinant Protein**
COL5A2 (Collagen Type V Alpha 2 Chain) is a critical component of type V collagen, a fibrillar collagen found predominantly in connective tissues. Type V collagen is essential for regulating the assembly and diameter of heterotypic collagen fibrils, particularly those formed with type I collagen, which contribute to the structural integrity of skin, tendons, bones, and other extracellular matrices. The COL5A2 gene encodes the α2 chain of type V collagen, which combines with α1 chains (COL5A1 or COL5A3) to form triple-helical procollagen molecules. These are enzymatically processed into mature collagen fibrils, playing a role in tissue organization and mechanical stability.
Recombinant COL5A2 protein is produced via genetic engineering, often using mammalian or insect cell systems to ensure proper post-translational modifications, such as hydroxylation and glycosylation, critical for collagen functionality. This engineered protein retains the structural and bioactive properties of native COL5A2. enabling researchers to study its interactions in vitro or in vivo.
Mutations in COL5A2 are linked to Ehlers-Danlos syndrome (EDS), a group of disorders characterized by skin hyperelasticity, joint hypermobility, and tissue fragility. Recombinant COL5A2 serves as a tool to investigate disease mechanisms, screen therapeutic agents, or engineer biomimetic scaffolds for regenerative medicine. Its applications extend to studying cell-matrix interactions, fibrosis, and wound healing, offering insights into tissue repair strategies. By mimicking natural collagen behavior, recombinant COL5A2 also aids in developing biocompatible materials for clinical use.
