Jagged 1 Protein (JAG1) Antibody (Biotin)

Background

Jagged-1 (JAG1) is a critical ligand within the Notch signaling pathway, a key cell-to-cell communication mechanism that regulates cellular differentiation, proliferation, and apoptosis. This pathway is pivotal during embryonic development and maintains tissue homeostasis in adults. JAG1, specifically, is one of the five canonical Notch ligands (alongside JAG2, DLL1, DLL3, and DLL4) and is highly involved in multiple developmental processes such as neurogenesis, vasculogenesis, and skeletal development. The interaction of JAG1 with Notch receptors triggers a series of proteolytic cleavages and releases the Notch intracellular domain (NICD), which translocates to the nucleus and activates target gene transcription. Dysregulation of JAG1 or aberrations in the Notch pathway are linked to congenital disorders, cancers, and other pathological conditions. In particular, mutations in JAG1 are associated with Alagille syndrome, a multisystem disorder affecting the liver, heart, and other organs.
