{PDOC00862} {PS50296; SUI1} {BEGIN} ********************************************** * Translation initiation factor SUI1 profile * ********************************************** In budding yeast (Saccharomyces cerevisiae), SUI1 is a translation initiation factor that functions in concert with eIF-2 and the initiator tRNA-Met in directing the ribosome to the proper start site of translation [1]. SUI1 is a protein of 108 residues. Close homologs of SUI1 have been found [2] in mammals, insects and plants. SUI1 is also evolutionary related to: - Hypothetical proteins from bacteria such as Escherichia coli (yciH) or Haemophilus influenzae (HI1225). - Hypothetical proteins from archaea such as Methanococcus jannaschii (MJ0463). Two eukaryotic proteins also seem to contain a C-terminal SUI1-like domain. These are: - Density-regulated protein (gene: DENR). This protein is found in mammals, insects, nematodes, plants and fungi. - Ligatin (gene: LGTN). This protein is found in mammals and insects. The profile we developed covers the entire C-terminal SUI1-like domain. -Sequences known to belong to this class detected by the profile: ALL. -Other sequence(s) detected in Swiss-Prot: NONE. -Last update: August 2003 / Pattern removed.
