Naked cuticle 2 (NKD2) is a human gene that encodes the protein Nkd2, one of the Naked cuticle (Nkd) family of proteins that regulate the Wnt signaling pathway.[1][2] Both Nkd1 and Nkd2 proteins can bind to Dishevelled proteins (DVL1, DVL2, DVL3), but only Nkd2 can bind to the EGF-ligand family member TGF alpha and regulate its polarized secretion in cultured epithelial cells.[3]
