| Background | The Y-box binding protein 1 (YB1) belongs to a family of evolutionarily conserved, multifunctional Y-box proteins that bind single-stranded DNA and RNA and function as regulators of transcription, RNA metabolism, and protein synthesis. YB1 binds to Y-box sequences (TAACC) found in multiple gene promoters and can positively or negatively regulate transcription. YB1 activates genes associated with proliferation and cancer, such as cyclin A, cyclin B1, matrix metalloproteinase-2 (MMP-2), and the multi-drug resistance 1 (MDR1) gene. YB1 represses genes associated with cell death, including the Fas cell death-associated receptor and the p53 tumor suppressor gene. It also interacts with the RNA-splicing factor SRp30c and stabilizes interleukin-2 (IL-2) mRNA upon induction of T lymphocytes by IL-2. The majority of YB1 protein localizes to the cytoplasm, with a minor pool found in the nucleus; however, nuclear localization appears to be critical for its role in promoting proliferation. Nuclear translocation is cell cycle regulated, with YB1 protein accumulating in the nucleus during G1/S phase. In addition, nuclear translocation is induced in response to extracellular stimuli such as hyperthermia and UV irradiation, or treatment of cells with thrombin, interferons, or insulin-like growth factor (IGF-I). Treatment of the MCF7 breast cancer cell line with IGF-I results in Akt-mediated phosphorylation of YB1 at Ser102, which is required for nuclear translocation of YB1 and its ability to promote anchorage-independent growth. Research studies have shown that YB1 is overexpressed in many malignant tissues, including breast cancer, non-small cell lung carcinoma, ovarian adenocarcinomas, human osteosarcomas, colorectal carcinomas, and malignant melanomas. Investigators have shown that nuclear YB1 expression correlates with high levels of proliferation, drug resistance, and poor tumor prognosis. |

保存條件：
YBX1 Rabbit Polyclonal Antibody (KO Validated) -20ºC保存，Western一抗稀釋液-20ºC或4ºC保存，一年有效。Western一抗稀釋液優(yōu)先推薦4ºC保存，長(zhǎng)期不使用可以考慮-20ºC保存，但凍融可能會(huì)導(dǎo)致出現(xiàn)輕微的渾濁和少量不溶物。
注意事項(xiàng)：
如果本抗體用于Western blot (WB)、免疫熒光(IF)、免疫細(xì)胞化學(xué)(ICC)等實(shí)驗(yàn)，請(qǐng)注意回收使用過(guò)的稀釋抗體。回收的抗體通常至少可以重復(fù)使用5-10次。稀釋后的抗體，包括已經(jīng)使用過(guò)的稀釋抗體，請(qǐng)4℃保存。
回收后重復(fù)使用的抗體，使用方法同新鮮稀釋的抗體。如果在重復(fù)使用過(guò)程中發(fā)現(xiàn)抗體出現(xiàn)輕微混濁現(xiàn)象，可以10,000g離心1-3分鐘，取上清用于后續(xù)檢測(cè)。如果回收的抗體出現(xiàn)明顯的絮狀物或長(zhǎng)霉長(zhǎng)菌等情況，則可以考慮廢棄該抗體。
提供的Western一抗稀釋液也可以用于免疫熒光(IF)、免疫組化(IHC)、免疫細(xì)胞化學(xué)(ICC)等適當(dāng)用途。如果希望獲得最佳的檢測(cè)效果，請(qǐng)考慮使用上述檢測(cè)專用的一抗稀釋液。
本產(chǎn)品僅限于專業(yè)人員的科學(xué)研究用，不得用于臨床診斷或治療，不得用于食品或藥品，不得存放于普通住宅內(nèi)。
為了您的安全和健康，請(qǐng)穿實(shí)驗(yàn)服并戴一次性手套操作。
