**Background of NUMB Antibody**
NUMB is a highly conserved adaptor protein crucial for cell fate determination, primarily known for its role in asymmetric cell division during development. It functions as a key regulator of Notch signaling by promoting the endocytic degradation of Notch receptors, thereby influencing cellular differentiation and tissue patterning. NUMB also interacts with other signaling pathways, including Hedgehog and p53. and participates in cell adhesion, polarity, and apoptosis. Structurally, NUMB contains multiple isoforms generated by alternative splicing, featuring phosphotyrosine-binding (PTB) and proline-rich domains that mediate interactions with various partners like CDH1. EGFR, and MDM2.
In cancer biology, NUMB acts as a tumor suppressor, with its loss or dysregulation linked to malignancies such as breast, lung, and colorectal cancers. NUMB antibodies are essential tools for studying its expression, localization, and functional roles. They are widely used in techniques like Western blotting, immunofluorescence, and immunohistochemistry to investigate NUMB's involvement in stem cell maintenance, neuronal development, and oncogenesis. However, due to isoform diversity, selecting antibodies with specificity for particular NUMB variants is critical for accurate experimental outcomes. Research continues to explore NUMB's therapeutic potential, particularly in targeting cancer stem cells and overcoming drug resistance.
