MA5-15239 targets CHK1 in WB applications and shows reactivity with Human and mouse samples.
The MA5-15239 immunogen is purified recombinant fragment of CHK1 expressed in E. Coli.
MA5-15239 detects CHK1 which has a predicted molecular weight of approximately 56kDa.
CHK1, also known as CHEK1, it is a kinase that phosphorylates cdc25, an important phosphatase in cell cycle control, particularly for entry into mitosis. Cdc25, when phosphorylated on serine 216 by chk1 becomes bound by an adaptor protein in the cytoplasm. Therefore it is inhibited from removing the inhibiting phosphate from MPF (mitotic/maturation promoting factor) added by Wee1. Consequently, a cell is prevented from entering mitosis. Chk1 can also phosphorylate p53 at Ser20 in vitro.
