Recombinant Human CHK1 Checkpoint Homolog (S. pombe), GST-tagged

• Cat.No.: CHEK1-4838H
• Product Overview: Recombinant full-length human CHEK1 was expressed by baculovirus in Sf9 insect cells using a N-terminal GST tag.

Specification

• Cat. No.: CHEK1-4838H
• Description: CHEK1 is a 56 kd serine/threonine protein kinase that was originally identified in fission yeast to play a role in activation of the DNA damage checkpoint in the G2 phase of the cell cycle. CHEK1 appears to function downstream of several of the known fission yeast checkpoint gene products, including that encoded by rad3+, a gene with sequence similarity to the ATM gene mutated in patients with ataxia telangiectasia.
