| 产品编号 | bs-8364R-Bio |
| 英文名称 | phospho-NIPA (Ser354) Rabbit pAb, Biotin conjugated |
| 中文名称 | Biotin标记的磷酸化间变性淋巴瘤激酶核相互作用伴侣蛋白抗体 |
| 英文别名 | NIPA(phospho S354); NIPA(phospho Ser354); p-NIPA(S354); p-NIPA(Ser354); hNIPA; Nuclear interacting partner of ALK; Nuclear interacting partner of anaplastic lymphoma kinase; ZC3HC1; Zinc finger C3HC type containing 1; NIPA_HUMAN. |
| 产品应用 | WB=1:500-2000 Not yet tested in other applications. |
| 抗体来源 | Rabbit |
| 免疫原 | KLH conjugated synthesised phosphopeptide derived from human NIPA around the phosphorylation site of Ser354 |
| 亚型 | IgG |
| 纯化方法 | affinity purified by Protein A |
| 克隆类型 | Polyclonal |
| 浓度 | 1mg/ml |
| 储存液 | 0.01M TBS (pH7.4) with 1% BSA, 0.02% Proclin300 and 50% Glycerol. |
| 研究领域 | Cell Biology > Proteolysis / Ubiquitin > Proteasome / Ubiquitin > Ubiquitin E3 Enzymes > SCF Complex E3 Ligase |
| 亚基 | Interacts with the NPM-ALK fusion protein in a tyrosine phosphorylation-dependent manner. Interacts with SKP1. Component of a SCF(NIPA) E3 complex with SKP1, RBX1 and CUL1 when not phosphorylated on Ser-354. Interacts with CCNB1. |
| 亚细胞定位 | Nuclear. |
| 组织特异性 | Widely expressed. Highly expressed in heart, skeletal muscle and testis. Expressed in brain, placenta, lung, kidney, liver, pancreas, spleen, thymus, prostate, ovary small intestine and colon. Weakly or not expressed in leukocytes. |
| 翻译后修饰 | hosphorylated. Phosphorylated on Ser residues at G2/M phase, but not during S and G0 phases. May also be weakly phosphorylated on Tyr residues. Ser-354 phosphorylation, a major site during the course of cell-cycle-dedendent phosphorylation, results in its dissociation from the SCF(NIPA) complex, thereby preventing CCNB1 degradation leading to mitotic entry. |
| 相似性 | Contains 1 C3HC-type zinc finger. |
| 功能 | Essential component of an SCF-type E3 ligase complex, SCF(NIPA), a complex that controls mitotic entry by mediating ubiquitination and subsequent degradation of cyclin B1 (CCNB1). Its cell-cycle-dependent phosphorylation regulates the assembly of the SCF(NIPA) complex, restricting CCNB1 ubiquitination activity to interphase. Its inactivation results in nuclear accumulation of CCNB1 in interphase and premature mitotic entry. May have an antiapoptotic role in NPM-ALK-mediated signaling events. |
| 保存条件 | Shipped at 4℃. Store at -20°C for one year. Avoid repeated freeze/thaw cycles. |
| 注意事项 | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications. |
| 背景资料 | The regulated oscillation of protein expression is an essential mechanism of cell cycle control. The SCF class of E3 ubiquitin ligases is involved in this process by targeting cell cycle regulatory proteins for degradation by the proteasome, with the F-box subunit of the SCF specifically recruiting a given substrate to the SCF core. NIPA (nuclear interaction partner of ALK) is a human F-box-containing protein that defines an SCF-type E3 ligase (SCFNIPA) controlling mitotic entry. Assembly of this SCF complex is regulated by cell-cycle-dependent phosphorylation of NIPA, which restricts substrate ubiquitination activity to interphase. Nuclear cyclin B1 is a substrate of SCFNIPA. Inactivation of NIPA by RNAi results in nuclear accumulation of cyclin B1 in interphase, activation of cyclin B1-Cdk1 kinase activity, and premature mitotic entry. Thus, SCFNIPA-based ubiquitination may regulate S-phase completion and mitotic entry in the mammalian cell cycle. |
