Abstract

Cripto-1, a co-receptor for Nodal, can activate Nodal-dependent and Nodal-independent signaling pathways. In this study we have investigated whether Cripto-1 mutants, that fail to activate a Nodal-dependent signaling pathway, are capable to activate a Nodal-independent signaling pathway in mammary epithelial cells. Cripto-1 mutants expressed in EpH4 mouse mammary epithelial cells are fully functional in regard to activation of a Nodal-independent signaling pathway, leading to phosphorylation of mitogen-activated protein kinase (MAPK) and Akt and to enhanced proliferation and motility of these cells, suggesting that Cripto-1 mutants with impaired Nodal signaling are still active in a Nodal-independent signaling pathway. Structured summary: MINT-6797299:Glypican 1 (uniprotkb:P35052) physically interacts (MI:0218) with Cr 1 (uniprotkb:P13385) by anti bait coimmunoprecipitation (MI:0006).
