| abstractText | The pleiotropic cytokine transforming growth factor-β (TGF-β) signals through different pathways among which the Smad- and the MAP-Kinase pathways are already well characterized. Both pathways utilize adaptor/chaperone molecules that facilitate or modulate the intracellular signaling events. Two of the proteins shown in vitro to play a role in Smad-dependent signaling are the TGF-β Receptor Associated Protein-1 (TRAP1, also TGFBRAP1) and its homologue VPS39, also known as Vam6 and TRAP1-Like-Protein (TLP). We generated mice deficient for TRAP1 and VPS39/TLP, respectively. Absence of TRAP1 protein results in death at either of two defined timepoints during embryogenesis, before the blastula stage or during gastrulation, whereas most of the VPS39 deficient mice die before E6.5. Heterozygous mice show no overt phenotype. In summary, our data indicate that TRAP1 and VPS39 are nonredundant and essentially required for early embryonic development. |
