The binding interaction of HMG-1 with the TATA-binding protein/TATA complex.
High mobility protein-1 (HMG-1) has been shown to regulate transcription by RNA polymerase II. In the context that it acts as a transcriptional repressor, it binds to the TATA-binding protein (TBP) to form the HMG-1/TBP/TATA complex, which is proposed to inhibit the assembly of the preinitiation complex. By using electrophoretic mobility shift assays, we show that the acidic C-terminal domain o...
متن کاملHigh Mobility Group 1 Protein (Hmg-1) Stimulates Proinflammatory Cytokine Synthesis in Human Monocytes
Lipopolysaccharide (LPS) is lethal to animals because it activates cytokine release, causing septic shock and tissue injury. Early proinflammatory cytokines (e.g., tumor necrosis factor [TNF] and interleukin [IL]-1) released within the first few hours of endotoxemia stimulate mediator cascades that persist for days and can lead to death. High mobility group 1 protein (HMG-1), a ubiquitous DNA-b...
متن کاملDoes high-mobility-group non-histone protein HMG 1 interact specifically with histone H1 subfractions?
The interaction of the non-histone chromosomal protein HMG (high-mobility group) 1 with histone H1 subfractions was investigated by equilibrium sedimentation and n.m.r. sectroscopy. In contrast with a previous report [Smerdon & Isenberg (1976) Biochemistry 15, 4242--4247], it was found, by using equilibrium-sedimentation analysis, that protein HMG 1 binds to all three histone H1 subfractions CT...
متن کاملSEPARATION OF NONHISTONE HIGH MOBILITY GROUP (HMG) FROM HUMAN LYMPHOCYTES BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY
The high mobility group (HMG) of nonhistone proteins have been investigated using two high performance liquid chromatographic techniques (HPLC). Reversed-phase HPLC under conditions of 50 mM triethylamine adjusted to pH 2.2 with phosphoric acid (solvent A) and 95% acetonitrile in water (solvent B) was used to separate proteins primarily on the basis of differences in the overall hydrophobi...
متن کاملThe isolation and identification of ubiquitin from the high mobility group (HMG) non-histone protein fraction.
Chromatin contains a group of non-histone chromosomal proteins called the high mobility group (HMG) proteins [l] . Four of the HMG proteins from calf thymus, HMG 1,2,14 and 17, and an HMG protein from trout testis, HMG-T, have been isolated in a pure form [2-51. The amino acid sequence of calf thymus HMG 17 has recently been determined [6] , and we have also shown that HMG proteins HMG 1,2, 14 ...
