Chromatin reorganization in rat spermatids during the disappearance of testis-specific histone, H1t, and the appearance of transition proteins TP1 and TP2.

Biology of Reproduction, 1996
Transition proteins replace testis-specific histones and are finally replaced by protamines in the nucleus of germ cells during spermiogenesis. In this study, immunoperoxidase and immunogold localization were used to determine both qualitatively and ...

A cytochemical study of the transcriptional and translational regulation of nuclear transition protein 1 (TP1), a major chromosomal protein of mammalian spermatids

Journal of Cell Biology, 1988
Immunocytochemical localization and in situ hybridization techniques were used to investigate the presence of spermatid nuclear transition protein 1 (TP1) and its mRNA during the various stages of spermatogenesis in the rat.

Identification of a functional cyclic adenosine 3',5'-monophosphate response element in the 5'-flanking region of the gene for transition protein 1 (TP1), a basic chromosomal protein of mammalian spermatids.

Biology of Reproduction, 1994
Transition protein 1 (TP1) is a small basic chromosomal protein that appears in mammalian spermatids during the period of chromatin condensation. The gene for TP1 from several species contains an apparent cAMP response element (CRE) in the immediate 5 ...

Storage Time and Temperature on the Sensory Properties Broccoli

Foods, 2019
Typically, broccoli arrives at the store within 7–14 days of harvest and is kept refrigerated until purchased or considered waste. To date, information has been limited on how this time on the shelf or storage temperature affects the sensory ...

Retrotransposon-like nature of Tp1 elements: implications for the organisation of highly repetitive, hypermethylated DNA in the genome of Physarum polycephalum.

Nucleic Acids Research, 1991
The repetitive fraction of the genome of the eukaryotic slime mould Physarum polycephalum is dominated by the Tp1 family of highly repetitive retrotransposon-like sequences.
