cdc2 (POH1) Mouse mAb #9116
|W IP IHC-P IF-IC||H Mk||Endogenous||34||Mouse IgG2a|
Reactivity Key: H=Human Mk=Monkey
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Specificity / Sensitivity
cdc2 (POH1) Mouse mAb detects endogenous levels of total cdc2 protein. The antibody does not cross-react with other cdks.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a recombinant human cdc2 fusion protein.

The entry of eukaryotic cells into mitosis is regulated by cdc2 kinase activation, a process controlled at several steps including cyclin binding and phosphorylation of cdc2 at Thr161 (1). However, the critical regulatory step in activating cdc2 during progression into mitosis appears to be dephosphorylation of cdc2 at Thr14 and Tyr15 (2). Phosphorylation at Thr14 and Tyr15, resulting in inhibition of cdc2, can be carried out by Wee1 and Myt1 protein kinases (3,4). The cdc25 phosphatase may be responsible for removal of phosphates at Thr14 and Tyr15 and subsequent activation of cdc2 (1,5).
