ERVK-21 antibody targets the envelope protein of human endogenous retrovirus K (HERV-K), specifically the HERV-K (HML-2) subgroup. HERVs are remnants of ancient retroviral infections integrated into the human genome, constituting ~8% of human DNA. While most HERVs are silenced or nonfunctional due to mutations, some, like HERV-K, retain partial activity and have been implicated in diseases, including cancer, autoimmune disorders, and neurodegenerative conditions. The HERV-K envelope (Env) protein, encoded by the *env* gene, plays roles in cell-cell fusion, immune modulation, and potential oncogenesis.
ERVK-21 antibody, typically a monoclonal IgG, is designed to detect HERV-K Env protein expression in research settings. It enables studies exploring HERV-K reactivation in pathological contexts, such as tumor microenvironments or inflammatory diseases. The antibody is validated for techniques like immunohistochemistry, Western blotting, and immunofluorescence. Its specificity helps elucidate HERV-K's contribution to disease mechanisms, including its interaction with host immune responses or promotion of cellular transformation.
Recent studies highlight HERV-K Env as a biomarker or therapeutic target, particularly in cancers like melanoma or glioblastoma. ERVK-21 antibody thus serves as a critical tool for investigating HERV-K's pathobiological roles and potential clinical applications. Ongoing research aims to clarify its diagnostic or therapeutic utility in diseases linked to aberrant HERV-K activity.
