Programmed cell death 4 (neoplastic transformation inhibitor); 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 (By similarity); Belongs to the PDCD4 family.
Synonyms: PDCD4, PDCD4p, hPDCD4, Q53EL6, Q5VZS7 ...
