  Function in Host
mRNA-binding protein involved in translation elongation. Has an importantfunction at the level of mRNA turnover, probably acting downstream ofdecapping. Criticalfor the efficient synthesis of peptide bonds between consecutiveproline residues. Can resolve ribosomal stalling caused by consecutive prolines duringtranslation. Involved in actin dynamics and cell cycle progression, mRNA decay andprobably in a pathway involved in stress response and maintenance ofcell wall integrity. With syntenin SDCBP, functions as a regulator ofp53/TP53 and p53/TP53-dependent apoptosis. Regulatesalso TNF-alpha-mediated apoptosis. Mediates effectsof polyamines on neuronal process extension and survival. May play an important role in brain development andfunction, and in skeletal muscle stem cell differentiation. Also described as a cellular cofactor of human T-cellleukemia virus type I (HTLV-1) Rex protein and of humanimmunodeficiency virus type 1 (HIV-1) Rev protein, essential for mRNAexport of retroviral transcripts.
