- Chang M, Chang J, Gangopadhyay A, Shearer A, Cadigan K. Activation of wingless targets requires bipartite recognition of DNA by TCF. Curr Biol. 2008;18:1877-81 pubmed publisher..Our data suggest that DNA recognition by fly TCF occurs through a bipartite mechanism, involving both the HMG domain and the C-clamp, which enables TCF to locate and activate WREs in the nucleus. ..
