SPRY1 Polyclonal Antibody

靶标信息

Sprouty-1 and -2 are membrane-anchored phosphoprotein inhibitors of growth factor signaling in endothelial cells. Four mammalian Sprouty homologues (Sprouty-1-4) have been identified. One study showed that overexpressed Sprouty-1 and -2 inhibits fibroblast growth factor and vascular endothelial growth factor-induced proliferation and differentiation by repressing pathways leading to MAP kinase activation. Sprouty proteins are also endogenous inhibitors of the Ras/MAP kinase pathway that play an important role in the remodeling of branching tissues, such as in development of the lung, kidney tubules, vascular system, and breast ducts. A recent study shows that Sprouty-1 and -2 may have tumor suppressing activity in the breast, and found that both proteins are consistently down-regulated in breast carcinomas.
