Protein scribble homolog (SCRIB)

Scaffold protein involved in various areas of polarized cells differentiation regulating epithelial and neuronal morphogenesis. Most likely functions in the creation of apico-basal cell polarity.

May function in cell proliferation regulating progression from G1 to S phase and as a positive regulator of apoptosis for example through acinar morphogenesis of the mammary epithelium. May also function in cell migration and adhesion and hence regulate cell invasion through MAPK signaling.
