NUMB Antibody

Numb is a protein that in humans is encoded by the gene of the same name. The encoded protein, whose degradation is induced in a proteasome-dependent manner by <a href=../search_result.php?search_txt=mdm>MDM2</a>, is a membrane-bound protein that has been shown to associate with EPS15, LNX1, and NOTCH1. The primary function of Numb in cell differentiation is as an inhibitor of <a href=../search_result.php?search_txt=notch>Notch</a> signaling which is essential for maintaining self-renewal potential in stem and progenitor cells. Numb also plays a crucial role in asymmetrical cell division during development, allowing for differential cell fate specification in the central and peripheral nervous systems. Additionally, the protein product controls binary cell fate decisions in the peripheral and central nervous systems of both invertebrates and mammals during neurogenesis.
