Applications Key: W=Western Blotting,

Specificity / Sensitivity

Phospho-cdc2 (Thr161) Antibody detects endogenous levels of cdc2 only when phosphorylated at threonine 161. The antibody cross-reacts with endogenous CDK2 phosphorylated at threonine 160. Phospho-cdc2 (Thr161) Antibody能够检测内源性苏氨酸(161位)磷酸化的cdc2蛋白,该抗体与内源性苏氨酸(160位)磷酸化的CDK2有交叉反应。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr161 of human cdc2. Antibodies are purified by protein A and peptide affinity chromatography. 该多克隆抗体是由合成的人源的针对cdc2蛋白苏氨酸(161位)磷酸化肽段免疫动物,采用A蛋白和多肽亲和层析方法纯化生产的。

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). cdc2蛋白激酶的激活参与调节真核细胞进入有丝分裂,cdc2的激活受多个步骤的调控,包括周期蛋白的结合、cdc2苏氨酸161位的磷酸化(1)。然而,在细胞进入有丝分裂的过程中,激活cdc2的决定性步骤是苏氨酸14位和15位的去磷酸化(2)。Wee1 和 Myt1蛋白激酶通过磷酸化cdc2苏氨酸14位和15位,抑制cdc2活性(3,4)。而cdc25磷酸酯酶可能起到使cdc2苏氨酸14位和15位去磷酸化从而激活cdc2的作用(1,5)。

cdc2 activation and association with cyclin A require phosphorylation at Thr161 by the CDK-activating kinase CAK, a complex of CDK7 and cyclin H (7,8). CAK磷酸化cdc2苏氨酸161位点后,cdc2才能够激活并协同cyclin A。CAK是CDK激活的激酶,是CDK7和cyclin H 的复合物(7,8)。
