Crystal Structure of the Human Ribosome in Complex with DENR-MCT-1.
The repertoire of the density-regulated protein (DENR) and the malignant T cell-amplified sequence 1 (MCT-1/MCTS1) oncoprotein was recently expanded to include translational control of a specific set of cancer-related mRNAs. DENR and MCT-1 form the heterodimer, which binds to the ribosome and operates at both translation initiation and reinitiation steps, though by a mechanism that is yet uncle...
متن کاملPost-transcriptional control of the MCT-1-associated protein DENR/DRP by RNA-binding protein AUF1.
BACKGROUND There is often a poor correlation observed between protein and RNA in eukaryotic systems, supporting the emerging pardigm that many of the abnormalities in a cancer cell's proteome may be achieved by differential recruitment of mRNAs to polysomes referred to as the translational profile. The MCT-1 oncogene product has recently been shown to interact with the cap complex and to modula...
متن کاملSynthesis and crystal structure of Zinc (II) Complex [Zn(25-MBTSC)2I2]
Zinc (II) complex, [Zn(25-MBTSC)2I2] (1), where (25-MBTSC = (E)-2-(2,5-dimethoxybenzaldehyde) thiosemicarbazone, has been synthesized from the reaction of ZnI2 with 25-MBTSC in methanol as solvent at 25 ºC. It was characterized by elemental analysis (CHN) and is confirmed by single-crystal X-ray diffraction analysis. The complex 1 crystallizes in a triclinic system, with space group P-ī, having...
متن کاملFeatures critical for membrane binding revealed by DivIVA crystal structure.
DivIVA is a conserved protein in Gram-positive bacteria that localizes at the poles and division sites, presumably through direct sensing of membrane curvature. DivIVA functions as a scaffold and is vital for septum site selection during vegetative growth and chromosome anchoring during sporulation. DivIVA deletion causes filamentous growth in Bacillus subtilis, whereas overexpression causes hy...
متن کاملActivities of Ligatin and MCT-1/DENR in eukaryotic translation initiation and ribosomal recycling.
Eukaryotic translation initiation begins with ribosomal recruitment of aminoacylated initiator tRNA (Met-tRNA(Met)(i)) by eukaryotic initiation factor eIF2. In cooperation with eIF3, eIF1, and eIF1A, Met-tRNA(Met)(i)/eIF2/GTP binds to 40S subunits yielding 43S preinitiation complexes that attach to the 5'-terminal region of mRNAs and then scan to the initiation codon to form 48S initiation comp...
