VIII. Mutations of the hisT Gene
نویسندگان
چکیده
The hisT gene, one of six genes in which mutation causes derepression of the histidine operon in Salmonella typhimurium, is shown to code for a protein that is not essential for the growth of the bacteria. This is indicated by the characterization of particular classes of mutations in the hisT gene: amber mutations, frameshift mutations, and temperature-sensitive mutations that affect repression but not growth. In addition, the class of semilethal mutations was selected for but not found.

Genotyping of Intron 22 and Intron 1 Inversions of Factor VIII Gene Using an Inverse-Shifting PCR Method in an Iranian Family with Severe Haemophilia A
Abstract Background: Haemophilia A (HA) is an X-linked bleeding disorder caused by the absence or reduced activity of coagulation factor VIII (FVIII). Coagulation factors are a group of related proteins that are essential for the formation of blood clots. The aim of this study was to genotype the coagulation factor VIII gene mutations using Inverse Shifting PCR (IS-PCR) in an Iranian family ...

متن کاملThe Effects of Novel Mutations in A1 Domain of Human Coagulation Factor VIII on Its Secretion Level in Cultured Mammalian Cells
Inefficient secretion of the human coagulation factor (hFVIII) in mammalian expression systems is one ofthe main causes of the hFVIII low expression level, attributed to its interaction with a chaperone known asBiP/GRP78. In order to improve secretion efficiency of the hFVIII, based on the higher secretion level of theporcine FVIII and analysis of the hFVIII A110 region, that ...
متن کاملGenetic characterization of the sufj frameshift suppressor in Salmonella typhimurium.
A new suppressor of +1 frameshift mutations has been isolated in Salmonella typhimurium. This suppressor, sufJ, maps at minute 89 on the Salmonella genetic map between the argH and rpo(rif) loci, closely linked to the gene for the ochre suppressor tyrU(supM). The suppressor mutation is dominant to its wild-type allele, consistent with the suppressor phenotype being caused by an altered tRNA spe...
متن کاملCombined Factor V and VIII Deficiency
This review summarizes current data on the pathomechanisms and new genetic findings of combined factor V and VIII deficiency (CF5F8D). Congenital haemorrhagic disorders characterized by deficiency of two clotting factors comprise an interesting group. Among dual coagulation disorders, CF5F8D is the most common type. For the first time combined factor V and VIII deficiency (F5F8D) was reported b...
