CHARACTERIZATION OF HIGH MOBILITY GROUP NONHISTONE PROTEINS FROM DIFFERENTIATED NEUROPHILIC GRANULOCYTES
The quantitative changes of the high mobility group (HMG) nonhistone chromosomal proteins in nondividing, differentiated peritoneal exudate neutrophils were identified by their solubility, electrophoretic mobility on both SDS and acetic acid gels, densitometric traces and elution profile on CM-sephadex. The results indicated that in neutrophils, HMGl undergoes a considerable reduction (80%...
متن کاملHigh mobility group proteins 1 and 2
Viral particles at the late stages of SV40 morphogenesis were examined for the presence of HMG proteins 1 and 2, by an lmmunochemical method involving the transfer of proteins from polyacrylamide gels to nitrocellulose membranes. It was found that these proteins are present in SV40 provirions, in which histone HI is still associated with viral chromatin, but absent in mature SV40 virions. INTRO...
متن کاملNonhistone Nuclear High Mobility Group Proteins
Nucleosome core particles form well defined complexes with the nuclear nonhistone proteins HMG 14 or 17. The binding of HMG 14 or 17 to nucleosomes results in greater stability of the nucleosomal DNA as shown by circular dichroism and thermal denaturation. Under appropriate conditions the binding is cooperative, and cooperativity is ionic strength dependent. The specificity and cooperative tran...
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 کاملSynthesis of high mobility group proteins in regenerating rat liver.
Incorporation of [3H]lysine into the non-histone chromosomal proteins HMG1, HMG2, and HMG17 and into each of the five major classes of histones was measured in rat liver at various times after partial hepatectomy. Histone synthesis was closely coupled temporally to that of DNA, although a small amount of histone was shown to be produced before DNA replication began. In contrast, the incorporati...
