EPB41L5 belongs to the band 4.1 superfamily. We investigate here the involvement of EPB41L5 in epithelial-mesenchymal transition (EMT) during mouse gastrulation. EPB41L5 expression is induced during TGFbeta-stimulated EMT, whereas silencing of EPB41L5 by siRNA inhibits this transition. In EPB41L5 mutants
