Biochem/physiol Actions

WS3 is a non-cell specific proliferative molecule thought to act primarily through modulating the activity of ErbB3-binding protein 1 (EBP1).
WS3 is a non-cell specific proliferative molecule, thought to act primarily through modulating the activity of ErbB3-binding protein 1 (EBP1) also known as proliferation-associated protein 2G4 (PA2G4), an RNA-binding protein that is involved in growth regulation and inhibition. It may alsohae some activity through the I?B kinase pathway. WS3 was initially found to be a proliferative molecule for β-cells, but more recently found to mediate proliferation of primary retinal pigment epithelial cells. After W3 removal, the retinal cells differentiated into a functional monolayer and remained functional in vivo, preserving vision when they were transplanted into RCS rats used as a model of retinal degeneration.
