PublicationsDou Y and Gorovsky MA. 2000. Phosphorylation of linker histone H1 regulates gene expression in vivo by creating a charge patch. Mol Cell 6(2):225-31.

Dou Y and Gorovsky MA. 2002. Regulation of transcription by H1 phosphorylation in tetrahymena is position independent and requires clustered sites. Proc Natl Acad Sci U S A 99(9):6142-6.
CommentsComplete somatic tranformant of CU428 cells with pQ5A5 /neo construct. Phosphorylation sites 1- 5 of H1 changed to alanines and 5 other sites changed to glutamines, neo 2 cassette in 3’ flanking region for selection. See paper.

From the Gorovsky lab, University of Rochester. This strain has been cataloged by the Stock Center but not thawed.
