Gene Information

goat ... Chk1(1111)

Immunogen

The epitope recognized by PLA0054 maps to a region between residues 200 and 250 of human Checkpoint Kinase 1 using the numbering given in entry NP_001265.1 (GeneID 1111).

Physical form

Tris-citrate/phosphate buffer, pH 7 to 8 containing 0.09% sodium azide

Other Notes

Chk1 functions as a checkpoint protein kinase that is critical to the regulation of the Cdc25a and Cdc25c phosphatases that promote S and G2/M phase progression, respectively. Chk1 kinase activity inhibits cell cycle progression in the presence of DNA damage by phosphorylating Cdc25a and Cdc25c and causing the degradation of Cdc25a and cytoplasmic sequestration of Cdc25c.

Wip1 (protein phosphatase Mg(2+)/Mn(2+)-dependent 1D, Ppm1d) is a nuclear serine/threonine protein phosphatase that is induced by p53 following the activation of DNA damage response (DDR) signaling. Ppm1d(-/-) mouse embryonic fibroblasts (MEFs) exhibit premature senescence under conventional culture conditions; however, little
