Structural basis for inhibition of translation by the tumor suppressor Pdcd4.
The tumor suppressor function of Programmed Cell Death 4 (Pdcd4) is achieved through interactions between Pdcd4 and components of the translation initiation complex, namely, the RNA helicase eIF4A and the scaffolding protein eIF4G. These interactions are mediated through two MA3 domains on the Pdcd4 molecule and result in inhibition of protein synthesis. We have solved the high-resolution cryst...
متن کاملinvestigating the integration of translation technologies into translation programs in iranian universities: basis for a syllabus design in translation technology
today, information technology and computers are indispensable tools of any profession and translation technologies have become an indispensable part of translator’s workstation. with the increasing demands for high productivity and speed as well as consistency and with the rise of new demands for translation and localization, it is necessary for translators to be familiar with market demands an...
Structural Basis for ASPP2 Recognition by the Tumor Suppressor p73
Tumor suppressors p53, p63 and p73 comprise a family of stress-responsive transcription factors with distinct functions in development and tumor suppression. Most human cancers lose p53 function, yet all three proteins are capable of inducing apoptosis or cellular senescence. Mechanisms are therefore under investigation to activate p73-dependent apoptosis in p53-deficient cancer cells. Signific...

An evolutionarily conserved interaction of tumor suppressor protein Pdcd4 with the poly(A)-binding protein contributes to translation suppression by Pdcd4
The tumor suppressor protein programmed cell death 4 (Pdcd4) has been implicated in the translational regulation of specific mRNAs, however, the identities of the natural Pdcd4 target mRNAs and the mechanisms by which Pdcd4 affects their translation are not well understood. Pdcd4 binds to the eukaryotic translation initiation factor eIF4A and inhibits its helicase activity, which has suggested ...
