Cripto/TDGF1 is a member of the epidermal growth factor (EGF)-Cripto , Frl-1 , and Cryptic (CFC) family. EGF-CFC family member proteins share a variant EGF-like motif , a conserved cysteine-rich domain , and a C-terminal hydrophobic region. Before gastrulation , Cripto is asymmetrically expressed in a proximal–distal gradient in the epiblast , and subsequently is expressed in the primitive streak and newly formed embryonic mesoderm. These proteins play key roles in intercellular signaling pathways during vertebrate embryogenesis. Mutations in Cripto/TDGF1 can cause autosomal visceral heterotaxy. Cripto/TDGF1 is involved in left-right asymmetric morphogenesis during organ development. Cripto signalling is essential for the conversion of a proximal–distal asymmetry into an orthogonal anterior–posterior axis. The mechanism of inhibitory effects of the Cripto includes both cancer cell apoptosis , activation of c-Jun-NH(2)-terminal kinase and p38 kinase signaling pathways and blocking of Akt phosphorylation. Thus , Cripto is a unique target , and Immunohistochemistry to Cripto could be of therapeutic value for Human cancers.
