On the presence of two new high mobility group-like proteins in HeLa S3 cells.
Two phosphorylated HMG-like proteins with Mr approximately 10 000 have been isolated from HeLa S3 cells, one being present in metaphase and one in interphase cells. The amino acid compositions of these proteins are very similar but differ from the known HMG proteins. However, they exhibit similarities being rich in proline, basic and acidic amino acids. A possible role in chromatin condensation of the HMG-like protein characteristic for metaphase cells is suggested.
