Human Supt5h protein, a putative modulator of chromatin structure, is reversibly phosphorylated in mitosis.

The Saccharomyces cerevisiae proteins Spt4p, Spt5p and Spt6p are involved in transcriptional repression by modulating the structure of chromatin. From HeLa cells we have purified a human homologue of Spt5p, Supt5hp, and show here that the protein is reversibly phosphorylated in mitosis. The cloned cDNA predicts a protein of 1087 residues with 31% identity to yeast Spt5p. It includes an acidic N-terminus, a putative nuclear localization signal and a C-terminal region containing two different repeated motifs. One of them, with the consensus sequence P-T/S-P-S-P-Q/A-S/G-Y, is similar to the C-terminal domain in the largest subunit of RNA polymerase II.[1]
