DAB2 Proteins and Enzymes

Disabled-2 (Dab2) is a component of the CSF-1 signal transduction pathway. Dab2 is involved in the regulation of cytoskeleton based functions by regulating cell positioning, inducing marcrophage adhesion, or regulation of protein trafficking of endocytosis involved proteins (1,2). Dab2 has been implicated in regulating the homeostasis of epithelial differentiation, where Dab2 is involved in endodermal cell formation, differentiation, and organization. Dab2 mRNA expression is common in normal ovarian epithelia cells but low or lack of expression is seen in ovarian carcinoma cell lines (3).
