Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation,


Species predicted to react based on 100% sequence homology: Monkey,

Specificity / Sensitivity

Phospho-NDRG1 (Thr346) Antibody detects endogenous levels of NDRG1 when phosphorylated at Thr346. This antibody likely cross-reacts with other conserved phosporylation sites on NDRG1 at positions Thr356 and Thr366.


Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr346 of NDRG1. Antibodies are purified by protein A and peptide affinity chromaography.

N-myc downstream-regulated gene 1 (NDRG1), also termed Cap43, Drg1, RTP/rit42, and Proxy-1, is a member of the NDRG family, which is composed of four members (NDRG1-4) that function in growth, differentiation, and cell survival (1-5). NDRG1 is ubiquitously expressed and highly responsive to a variety of stress signals including DNA damage (4), hypoxia (5), and elevated levels of nickel and calcium (2). Expression of NDRG1 is elevated in N-myc defective mice and is negatively regulated by N- and c-myc (1,6). During DNA damage, NDRG1 is induced in a p53-dependent fashion and is necessary for p53-mediated apoptosis (4,7). Research studies have shown that NDRG1 may also play a role in cancer progression by promoting differentiation, inhibiting growth, and modulating metastasis and angiogenesis (3,4,6,8,9). Nonsense mutation of the NDRG1 gene has been shown to cause hereditary motor and sensory neuropathy-Lom (HMSNL), which is supported by studies demonstrating the role of NDRG1 in maintaining myelin sheaths and axonal survival (10,11). NDRG1 is up-regulated during mast cell maturation and its deletion leads to attenuated allergic responses (12). Both NDRG1 and NDRG2 are substrates of SGK1, although the precise physiological role of SGK1-mediated phosphorylation is not known (13). NDRG1 is phosphorylated by SGK1 at Thr328, Ser330, Thr346, Thr356, and Thr366. Phosphorylation by SGK1 primes NDRG1 for phosphorylation by GSK-3.

N-myc下游调控gene1(NDRG1),也被称为Cap43,Drg1,RTP/rit42和Proxy-1,是NDRG家族的一员,该家族包含的4个成员(NDRG1-4)在生长,分化和细胞存活过程中发挥作用(1-5)。广泛表达的NDRG1并对多种压力信号发生应激反应,包括DNA损伤(4),缺氧(5),和镍及钙浓度升高(2)。NDRG1在N-myc缺陷小鼠中表达升高,能够被N-和c-myc负调控(1-6)。在DNA损伤过程中,NDRG1通过p53信号激活,并且是p53介导的凋亡过程中所必须的(4,7)。研究显示,NDRG1通过促进分化,抑制生长,调控血管生成和肿瘤转移等进程中发挥功能(3,4,6,8,9)。NDRG1基因发生无义突变后会引发遗传性运动和感觉神经病病变-Lom(HMSNL),该结论由证明NDRG1在维持髓鞘和轴突存活的研究支持(10,11)。NDRG1在肥大细胞成熟过程中表达上调,它的缺失会导致衰减的过敏反应(12)。NDRG1和NDRG2都是SGK1的底物,尽管SGK1介导的磷酸化的生理性作用尚未可知(13)。NDRG1可以被SGK1在Thr328, Ser330, Thr346, Thr356,以及Thr366磷酸化。NDRG1被SGK1磷酸化后可以被GSK-3磷酸化。

Phospho-NDRG1 (Thr346) Antibody is directed at a site that was identified at Cell Signaling Technology (CST) using PhosphoScan®, CST's LC-MS/MS platform for modification site discovery. Phosphorylation at Thr346 was discovered using an Akt substrate antibody and was shown to be induced by insulin treatment in multiple cell lines.
