Comparative studies on microinjected high-mobility-group chromosomal proteins, HMG1 and HMG2
The nonhistone chromosomal proteins, HMG1 and HMG2, were iodinated and introduced into HeLa cells, bovine fibroblasts, or mouse 3T3 cells by erythrocyte-mediated microinjection. Autoradiographic analysis of injected cells fixed with glutaraldehyde consistently showed both molecules concentrated within nuclei. Fixation with methanol, on the other hand, resulted in some leakage of the microinject...
متن کاملHigh mobility group (HMG) non-histone chromosomal proteins HMG1 and HMG2 are significant target antigens of perinuclear anti-neutrophil cytoplasmic antibodies in autoimmune hepatitis.
BACKGROUND High mobility group (HMG) non-histone chromosomal proteins HMG1 and HMG2 have been identified as novel antigens of perinuclear anti-neutrophil cytoplasmic antibodies (p-ANCAs), and the existence of anti-HMG1 and anti-HMG2 antibodies in a population of patients with ulcerative colitis has been reported. AIMS To investigate whether HMG1 and HMG2 are target antigens for p-ANCAs in aut...
متن کاملHigh-mobility group chromosomal proteins of wheat.
Four proteins have been extracted from purified chromatin of wheat embryos with 0.35 M NaCl. These proteins are soluble in 2% (w/v) trichloroacetic acid and thus meet the original operational requirements to be classified as "high-mobility group" (HMG) chromosomal proteins. The proteins have been characterized by one- and two-dimensional electrophoresis, amino acid analysis, and peptide mapping...
متن کاملNucleotide sequence of a mouse cDNA encoding the nonhistone chromosomal high mobility group protein-1 (HMG1)
The high mobility group (HMG) proteins are the major nonhistone components of chromatin (1). Among these, the HMG1 and HMG2 proteins are the most abundant; however, their precise function remains undefined. There are some indications for a putative role of HMG 1/2 in chromatin assembly (2), DNA replication (3) or even as general transcription factors for RNA polymerase II (4). There is a consid...
متن کاملA close relative of the nuclear, chromosomal high-mobility group protein HMG1 in yeast mitochondria.
ABF2 (ARS-binding factor 2), a small, basic DNA-binding protein that binds specifically to the autonomously replicating sequence ARS1, is located primarily in the mitochondria of the yeast Saccharomyces cerevisiae. The abundance of ABF2 and the phenotype of abf2- null mutants argue that this protein plays a key role in the structure, maintenance, and expression of the yeast mitochondrial genome...
