EN1 (Engrailed 1) is a homeodomain-containing transcription factor encoded by the *EN1* gene, which plays a critical role in embryonic development, particularly in the patterning of the central nervous system (CNS) and limb formation. During neurogenesis, EN1 is essential for midbrain-hindbrain boundary specification and the survival of dopaminergic neurons. It also regulates cell fate determination and tissue morphogenesis in developing limbs. Dysregulation of EN1 has been implicated in various pathological conditions, including cancers such as breast cancer, neuroblastoma, and medulloblastoma, where it may promote tumor progression, invasion, or drug resistance.
EN1 antibodies are immunological tools designed to detect and quantify EN1 protein expression in research applications. These antibodies are widely used in techniques like Western blotting, immunohistochemistry (IHC), and immunofluorescence (IF) to study EN1's spatial-temporal expression patterns, cellular localization, and functional roles in development and disease. In cancer research, EN1 antibodies help assess its potential as a diagnostic or prognostic biomarker. Commercially available EN1 antibodies are typically raised in hosts like rabbits or mice, targeting specific epitopes of the human or mouse EN1 protein. Validation parameters include reactivity across species, specificity in knockout models, and consistency in multiple assay platforms. Ongoing studies continue to explore EN1's therapeutic targeting potential, underscoring the antibody's relevance in both basic and translational research.
