Cripto-1 (CR-1)/Teratocarcinoma-derived growth factor1 (TDGF-1) is a cell surface
glycosylphosphatidylinositol (GPI)-linked glycoprotein that can function either
in cis (autocrine) or in trans (paracrine). The cell membrane cis form is found
in lipid rafts and endosomes while the trans acting form lacking the GPI anchor
is soluble. As a member of the epidermal growth factor
(EGF)/Cripto-1-FRL-1-Cryptic (CFC) family, CR-1 functions as an obligatory
co-receptor for the transforming growth factor-? (TGF-?) family members, Nodal
and growth and differentiation factors 1 and 3 (GDF1/3) by activating Alk4/Alk7
signaling pathways that involve Smads 2, 3 and 4. In addition, CR-1 can activate
non-Smad-dependent signaling elements such as PI3K, Akt and MAPK. Both of these
pathways depend upon the 78kDa glucose regulated protein (GRP78). Finally, CR-1
can facilitate signaling through the canonical Wnt/?-catenin and Notch/Cbf-1
pathways by functioning as a chaperone protein for LRP5/6 and Notch,
respectively. CR-1 is essential for early embryonic development and maintains
embryonic stem cell pluripotentiality. CR-1 performs an essential role in the
etiology and progression of several types of human tumors where it is expressed
in a population of cancer stem cells (CSCs) and facilitates
epithelial-mesenchymal transition (EMT). In this context, CR-1 can significantly
enhance tumor cell migration, invasion and angiogenesis. Collectively, these
facts suggest that CR-1 may be an attractive target in the diagnosis, prognosis
and therapy of several types of human cancer.
