Our studies demonstrate that many mutations affect trnam nuclear transport, although those with the most deleterious effects are clustered in the highly conserved D stem-loop and T stem-loop regions. Introduction In eukaryotic cells mature trna species are transported from the nucleus to the cytoplasm. trna nuclear transport: Defining the critical regions of mutagenesis trna nuclear transport defining the critical regions of human trnaimet by point mutagenesis Academia.edu is a platform for academics to share research papers. (PDF) biochemistry Seyda Gokyer - Academia.edu trna nuclear transport defining the critical regions of human trnaimet by point Trna Nuclear Transport Defining The Critical Regions Of mutagenesis We recently described a carrier-mediated nuclear transport system for trna in Xenopus laevis oocytes. A natural human trnaimet variant with a G to T transversion in position 57 is defective in transport across the nuclear membrane. In addition, processing of the primary transcript of the variant gene is much less efficient than the wild type. trna nuclear transport: Defining the critical regions of mutagenesis trna Nuclear Transport: Defining the Critical Regions of Human trnapt /85/l $ by Point Mutagenesis Janet Ash Tobian, Lee Drinkard, and Michael Z&off Human Genetics Branch National Institute of Child Health and Human Development Building 10, Room 8C-429 Bethesda, Maryland Cell, Vol. 43, , December 1985 (Part l), Copyright mutagenesis trna nuclear transport in this cell resembles a carrier-mediated translocation process rather than diffusion through a simple pore or channel. trna transport is saturable by trna, with a maximal rate measured to be about 190 X 10(7) molecules per min per nucleus (21 degrees C) in the mature oocyte. trna transport from the nucleus in a eukaryotic cell mutagenesis This could, in principle, be achieved by nuclear retention of immature trna or by selective export of the fully mature form. We show that exportin-t has a strong preference for trna with correctly processed 5' and 3' ends and nucleoside modification. trna recognition by exportin-t can thus be considered as a quality control mechanism for these...

Nuclear Export of trna SpringerLink mutagenesis Los1p and Pus1p, which are involved in trna biogenesis, were found in a genetic screen for components interacting with the nuclear pore protein Nsp1p. LOS1, PUS1 and NSP1 interact functionally, since the combination of mutations in the three genes causes synthetic lethality. Pus1p is an intranuclear... Nuclear pore proteins are involved in the biogenesis of mutagenesis Abstract. Although trna was the first substrate whose export from the nuclei of eukaryotic cells had been shown to be carrier-mediated and active, it has only been in the last 2 years that the first mechanistic details of this nucleocytoplasmic transport pathway have begun to emerge.
