Excerpt
PLU-1/Jarid1B is a nuclear protein that is widely expressed in breast cancer, with higher levels being seen in ER+ cancers. Expression in normal adult issues is largely restricted to testis and the differentiating mammary gland. Through the JmjC domain the protein can demethylate H3K4me3, which correlates with its function as a transcriptional repressor. PLU-1/Jarid1B contains a DNA binding domain, and can be recruited to DNA through binding to transcription factors. We now find that the protein interacts with the ERα receptor and contributes to estrogen-induced survival of MCF-7 cells in in vitro culture and when grown as tumours in nude mice. …
