DMP1 protein (SJ-96-0010)
Description The cyclin D-binding Myb-like protein DMP1 is a tumor suppressor. DMP1 binding to DNA activates transcription, which can be inhibited by direct binding of D-type cyclins. Similar to p19ARF, DMP1 inhibits cell cycle progression and DMP1 knockout mice develop cancers either spontaneously or more readily following exposure to chemical carcinogens or ionizing radiation.  Like p19ARF, DMP1 and its analogs may serve as potential prodrugs for cancer therapy as well as be valid targets in anti-cancer drug screening assays. Additionally, DMP1 may be used to regulate transcription of recombinant genes in mammalian cells.
Keywords  Tumor suppressor, cancer therapy prodrug, basic research material for transcriptional activation, cancer drug screening target.
