Recombinant human chromosomal proteins HMG-14 and HMG-17.
Vectors for expressing human chromosomal proteins HMG-14 and HMG-17 in bacterial cultures under the control of the temperature-inducible lambda PL promoter have been constructed. The open reading frames of the cDNAs have been amplified by the polymerase chain reaction (PCR), utilizing amplimers containing desired restriction sites, thereby facilitating precise location of the initiation codon d...
متن کاملExpression of chromosomal proteins HMG-14 and HMG-17 in transformed human cells.
The relation between cellular phenotype and expression of chromosomal high mobility group proteins 14 and 17 (HMG-14 and HMG-17) has been examined in human cell lineages. Quantitation of HMG-14 and HMG-17 mRNA in several human cell lines revealed differences in both the steady state mRNA level and in the ratio of HMG-14 to HMG-17 mRNA. Analysis of phenotypically distinct derivatives of human br...
متن کاملPersistence of chromosomal proteins HMG-14/-17 in myotubes following differentiation-dependent reduction of HMG mRNA.
The expression of chromosomal proteins HMG-14 and HMG-17 during cellular differentiation was studied in cultured mouse myoblasts. During myogenesis the level of both HMG-14 and HMG-17 mRNA decreased to less than 20% of that found in myoblasts. The down-regulation of HMG-14/-17 mRNA occurred simultaneously with activation of muscle-specific actin mRNA and was not linked to DNA synthesis, indicat...
متن کاملChromosomal Proteins HMG-14 and HMG-17 Are Released from Mitotic Chromosomes and Imported into the Nucleus by Active Transport
The high mobility group 14/17 (HMG-14/-17) proteins form specific complexes with nucleosome core particles and produce distinct footprints on nucleosomal DNA. Therefore, they could be an integral part of the chromatin fiber. Here we show that during the cell cycle these proteins are transiently dissociated from chromatin. They colocalize with the nuclear DNA in interphase and prophase but not i...
متن کاملEffect of high mobility group nonhistone proteins HMG-20 (ubiquitin) and HMG-17 on histone deacetylase activity assayed in vitro.
We have used a method previously described by Reeves and Candido (1) to partially release histone deacetylase from cell nuclei together with putative regulators of the enzyme. Histone deacetylase released from testis cell nuclei and its putative regulators were separated by gel filtration in Sepharose 6B. A peak of low molecular weight contains a heat-stable factor that stimulate histone deacet...
