Disease

PDCD4_MOUSE Note=Decreases benign tumor development and malignant progression.

Function

PDCD4_MOUSE Inhibits translation initiation and cap-dependent translation. May excert its function by hindering the interaction between EIF4A1 and EIF4G. Inhibits the helicase activity of EIF4A. Modulates the activation of JUN kinase. Down-regulates the expression of MAP4K1, thus inhibiting events important in driving invasion, namely, MAPK85 activation and consequent JUN-dependent transcription. May play a role in apoptosis. Tumor suppressor. Inhibits tumor promoter-induced neoplastic transformation. Binds RNA.^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

Programmed cell death protein 4 (Pdcd4) is a novel tumour suppressor protein, which is involved in the control of eukaryotic transcription and translation. The regulation of translation involves specific interactions with eukaryotic initiation factor (eIF)4A and eIF4G, which are mediated via the two tandem MA-3 domains. We have determined the structure of the C-terminal MA-3 domain of Pdcd4 (Pdcd4 MA-3(C)), characterized its interaction with eIF4A and compared the features of nuclear magnetic resonance (NMR) spectra obtained from the single domain and tandem MA-3 region. Pdcd4 MA-3(C) is composed of three layers of helix-turn-helix hairpins capped by a single helix and shows close structural homology to the atypical HEAT repeats found in many eIFs. The sequence conservation and NMR data strongly suggest that the tandem MA-3 region is composed of two equivalent domains connected by a somewhat flexible linker. Pdcd4 MA-3(C) was found to interact with the N-terminal domain of eIF4A through a conserved surface region encompassing the loop connecting alpha5 and alpha6 and the turn linking alpha3 and alpha4. This site is strongly conserved in other MA-3 domains known to interact with eIF4A, including the preceding domain of Pdcd4, suggesting a common mode of binding.
