Several DNA binding motifs have been described in the C-terminus of histone H1 (Churchill & Travers, 1991), of these the S/TPKK repeat (Suzuki, 1989) often occurs as a part of an octapeptide repeat of the type XTPKKXKK. ...

Several drugs are known to induce the liver microsomal mixed-function oxidase system when administered in vivo or even in vitro in cell culture. A sequence of events has been suggested in which the drug is visualized to ...

Spermatidal transition protein, TP2, was purified from rat testes by Hg-affinity chromatography. The present study reports the details of the zinc-metalloprotein nature of TP2 by employing the Zn-65-blotting technique. ...

A comparison of the DNase I digestion products of the 32P-5’-end-labeled pachytene nucleosome core particles (containing histones H2A, TH2A, X2, H2B, THPB, H3a, nd H4) and liver nucleosome core particles (containing somatic ...

Spermatidal protein TP2, which appears transiently during stages 12-16 of mammalian spermiogenesis, is a DNA condensing zinc metalloprotein with a preference to GC-rich DNA. We have carried out a detailed site-directed ...

Noncoding RNAs constitute a huge repertoire of gene regulatory molecules. Our previous, fine-resolution characterization of a mouse meiotic recombination hotspot from chromosome 8 resulted in identification of 2.4-kb ...

Successive administrations of allylisopropylacetamide, a potent porphyrinogenic drug, increase liver weight, microsomal protein and phospholipid contents. There is an increase in the rate of microsomal protein synthesis ...

Meiotic recombination occurs preferentially at certain regions called hot spots and is important for generating genetic diversity and proper segregation of chromosomes during meiosis. Hot spots have been characterized most ...

Pachytene nuclei were isolated from rat testes by the unit gravity sedimentation technique and contained histone variants H1a, H1t, TH2A, TH2B, and X2 in addition to the somatic histones H1bde, H1c, H2A, H2B, H3, and H4. ...

In eukaryotes, histone H1 promotes the organization of polynucleosome filaments into chromatin fibers, thus contributing to the formation of an important structural framework responsible for various DNA transaction processes. ...
