ADAM28 recombinant protein is derived from ADAM28 (A Disintegrin and Metalloprotease 28), a member of the ADAM family of transmembrane proteins. These proteins are characterized by a conserved domain structure, including a prodomain, metalloproteinase domain, disintegrin-like domain, cysteine-rich region, epidermal growth factor (EGF)-like domain, and a transmembrane segment. ADAM28 exists in two isoforms: a membrane-bound form (ADAM28-M) and a secreted form (ADAM28-S), generated via alternative splicing. It is primarily expressed in immune cells, such as lymphocytes and macrophages, as well as in certain cancer tissues, including lung and breast carcinomas.
Functionally, ADAM28 exhibits metalloproteinase activity, enabling proteolytic processing of extracellular matrix (ECM) components and cell surface proteins. It plays roles in cell adhesion, migration, and signaling by interacting with integrins or shedding cytokines and growth factors. In cancer, ADAM28 is implicated in tumor progression, metastasis, and immune evasion by modulating ECM remodeling and cell-cell communication. Its overexpression correlates with poor prognosis in several malignancies. Additionally, ADAM28 may regulate immune responses, potentially influencing autoimmune diseases like rheumatoid arthritis.
The recombinant ADAM28 protein is engineered for research applications, often produced in mammalian or insect cell systems to preserve post-translational modifications and enzymatic activity. It serves as a tool to study substrate specificity, enzymatic kinetics, and inhibitor screening. Researchers also utilize it to investigate ADAM28's role in disease pathways, validate its interactions with therapeutic antibodies, or develop diagnostic biomarkers. Its recombinant form enables controlled in vitro and in vivo studies, aiding the exploration of its dual roles in physiology and pathology.
