Specificity / Sensitivity

Phospho-p90RSK (Thr573) Antibody detects endogenous p90RSK protein only when phosphorylated at Thr573.

Phospho-p90RSK (Thr573) Antibody兔多抗能够检测内源性Thr573位点磷酸化的p90RSK蛋白水平。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr573 of human p90RSK. Antibodies are purified by protein A and peptide affinity chromatography.

The 90 kDa ribosomal S6 kinases (RSK1-4) are a family of widely expressed serine/threonine kinases characterized by two nonidentical, functional kinase domains (1) and a carboxy-terminal docking site for extracellular signal-regulated kinases (ERKs) (2). Several sites both within and outside of the RSK kinase domain, including Ser380, Thr359, Ser363, and Thr573, are important for kinase activation (3). RSK1-3 are activated via coordinated phosphorylation by MAPKs, by autophosphorylation, and by phosphoinositide-3-OH kinase (PI3K) in response to many growth factors, polypeptide hormones, and neurotransmitters (3).

90kDa核糖体S6激酶(RSK1-4)是一个广泛表达的丝/苏氨酸激酶家族,其特征是包含2个不同的功能性激酶结构域(1)和一个羧基端的细胞外信号调节激酶(ERKs)结合位点(2)。RSK激酶结构域内或以外的一些位点,包括Ser380, Thr359, Ser363和Thr573,对于激酶的激活非常重要(3)。RSK1-3在多种生长因子、多肽激素和神经递质的刺激下,通过MAPKs的磷酸化作用、自磷酸化作用以及PI3K的信号途径的协同作用被激活(3)。
