Target Background

GPI-anchored cell membrane protein involved in Nodal signaling. Cell-associated TDGF1 acts as a Nodal coreceptor in cis. Shedding of TDGF1 by TMEM8A modulates Nodal signaling by allowing soluble TDGF1 to act as a Nodal coreceptor on other cells. Could play a role in the determination of the epiblastic cells that subsequently give rise to the mesoderm.
Gene References into Functions
  1. Cripto-1 expression is increased by OCT4 overexpression, but decreased by shRNA-mediated OCT4 knockdown. OCT4 overexpression significantly activates Cripto-1 transcriptional activity. A 5'-upstream minimal promoter sequence in the gene-encoding Cripto-1 is significantly activated by OCT4 overexpression. PMID: 29223130
