Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting,

Specificity / Sensitivity

Phospho-PRK1 (Thr774)/ PRK2 (Thr816) Antibody detects endogenous levels of PRK1 and PRK2 only when phosphorylated at Thr774 or Thr816, respectively. This antibody also detects PKC zeta and lambda when phosphorylated at Thr 410 and 403, respectively.

Phospho-PRK1 (Thr774)/ PRK2 (Thr816)抗体识别内源性的Thr774磷酸化PRK1蛋白或Thr816磷酸化的PRK2蛋白。它也可以识别Thr410磷酸化的PKCζ和Thr403磷酸化的PKCλ。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr774 of human PRK1. Antibodies are purified by protein A and peptide affinity chromatography.


Western Blotting

Western Blotting

Western blot analysis of extracts from Jurkat cells, untreated or calf intestinal alkaline phosphotase (CIP)-treated, and 293 cells, untreated or calyculin A-treated, using Phospho-PRK1 (Thr774)/PRK2 (Thr816) Antibody (upper) or PRK1/PRK2 antibody (lower).

对Jurkat细胞(未处理,或小牛肠碱性磷酸酶(CIP)处理)和293细胞(未处理或calyculin A处理),使用Phospho-PRK1 (Thr774)/PRK2 (Thr816)抗体(上图)或PRK1/PRK2抗体(下图)进行Western blot分析。


The protein kinase C-related kinases (PRKs) are a subfamily of Ser/Thr-specific kinases with a catalytic domain highly homologous to the PKC family (1-3). They are effectors of Rho family GTPases (4-6) and are activated by fatty acids and phospholipids in vitro (7,8). Activation in vitro and in vivo involves the activation loop phosphorylation of PRK1 (Thr774)/PRK2 (Thr816) by PDK1 (9,10).

蛋白激酶C相关激酶(PRKs)是一种丝氨酸/苏氨酸特异性激酶亚家族,具有与PKC家族具有高度同源性的催化结构域(1-3)。它们是Rho家族GTP酶的效应物(4-6),在体外由脂肪酸和磷脂激活(7,8)。体外和体内的激活涉及PDK1磷酸化修饰PRK1 (Thr774)/PRK2 (Thr816)的活性环(9,10)。
