Background

Disabled homolog 2 (Dab2) is a mitogen responsive phosphoprotein that exerts multiple functions through association with numerous proteins. Dab2 modulates signaling pathways through interactions with proteins such as Smads and TGF-β receptors (1,2), axin (3), GRB (4), and Src (5). Dab2 also serves as a cargo-specific adaptor of clathrin-mediated endocytosis via interaction with clathrin (6), AP2 (7), NPXY-containing cargo (8-10), and myosin VI (11,12). In addition, Dab2 regulates cell adhesion by directly binding integrins (13,14). The diverse functions of Dab2 enable it to coordinate cell adhesion, cell motility, membrane trafficking, and signaling. Research studies have shown Dab2 is downregulated in a number of cancers, thereby suggesting a role as a tumor suppressor (15-17). Phosphorylation of Dab2 decreases its endocytotic function (18).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
