In Western blot a band is seen at ~18 kDa representing the core form of Cripto1, and at ~36 kDa reporesenting the glycosylated/ post-translationally modified form.
Suggested positive control: MDA-MB231 (human breast cancer) lysates.
Cripto (TDGF1) is a GPI-anchored cell membrane proetin involved in Nodal signaling. Cell associated TDGF1 acts as a a Nodeal coreceptor in cis. Shedding of TDGF1 by TMEM8A modulated Nodal signaling by allowing soluble TDGF1 to act as a Nodal coreceptor on other cells. TDGF1 is expressed both in ES cells and during the early phases of embryo development, while in adults it is reactivated in a wide range of epithelial cancers.
