Description of YPL127C: Histone H1, linker histone with roles in meiosis and sporulation; decreasing levels early in sporulation may promote meiosis, and increasing levels during sporulation facilitate compaction of spore chromatin; binds to promoters and within genes in mature spores; may be recruited by Ume6p to promoter regions, contributing to transcriptional repression outside of meiosis; suppresses DNA repair involving homologous recombination[1][2][3][4][5][6][7][8][9]

We analyzed a chromatin region of the yeast Chromosome (Chr) IX, in which there are two closely packed open reading frames (ORFs), POT1 and YIL161w. This locus shows a regular ladder of 13 stochastically positioned nucleosomes, which is unaffected by the absence of the HHO1 gene. This suggests that histone H1 has no effect on nucleosome positioning in yeast. [8] [10]
