Inversin (Invs)

Required for normal renal development and institution of left-right axis. Probably functions as a molecular switch between distinct Wnt signaling pathways.

Inhibits the canonical Wnt pathway by targeting cytoplasmic disheveled (DVL1) for degradation by the ubiquitin-proteasome. This suggests it is needed in renal growth to oppose the repression of terminal differentiation of tubular epithelial cells by Wnt signaling (By similarity).
