产品介绍 Rb is a tumor suppressor gene which functions as a negative regulator of the cell cycle by interacting with transcription factors including E2F1, PU1, ATF2, UBF, Elf1 and cAbl. This ability of Rb to alter transcription is regulated by phosphorylation catalyzed by the cyclin dependent protein kinases (cdks). Rb is phosphorylated on serine and threonine, but not on tyrosine residues. It forms a complex with SV40 large T antigen, adenovirus E1A, and human papilloma virus 16E. Rb protein may act by regulating transcription and loss of its function leads to uncontrolled cell growth. Aberrations in the Rb gene have been implicated in cancers of breast, colon, prostate, kidney, nasopharynx, and leukemia.
Function : Key regulator of entry into cell division that acts as a tumor suppressor. Promotes G0-G1 transition when phosphorylated by CDK3/cyclin-C. Acts as a transcription repressor of E2F1 target genes. The underphosphorylated, active form of RB1 interacts with E2F1 and represses its transcription activity, leading to cell cycle arrest. Directly involved in heterochromatin formation by maintaining overall chromatin structure and, in particular, that of constitutive heterochromatin by stabilizing histone methylation. Recruits and targets histone methyltransferases SUV39H1, SUV420H1 and SUV420H2, leading to epigenetic transcriptional repression. Controls histone H4 'Lys-20' trimethylation. Inhibits the intrinsic kinase activity of TAF1. Mediates transcriptional repression by SMARCA4/BRG1 by recruiting a histone deacetylase (HDAC) complex to the c-FOS promoter. In resting neurons, transcription of the c-FOS promoter is inhibited by BRG1-dependent recruitment of a phospho-RB1-HDAC1 repressor complex. Upon calcium influx, RB1 is dephosphorylated by calcineurin, which leads to release of the repressor complex (By similarity). In case of viral infections, interactions with SV40 large T antigen, HPV E7 protein or adenovirus E1A protein induce the disassembly of RB1-E2F1 complex thereby disrupting RB1's activity.
Subunit : Interacts with ATAD5. Interacts with PRMT2, CDK1 and CDK2. The hypophosphorylated form interacts with and sequesters the E2F1 transcription factor. Interacts with heterodimeric E2F/DP transcription factor complexes containing TFDP1 and either E2F1, E2F3, E2F4 or E2F5, or TFDP2 and E2F4. The unphosphorylated form interacts with EID1, ARID3B, KDM5A, SUV39H1, MJD2A/JHDM3A and THOC1. Interacts with the N-terminal domain of TAF1. Interacts with AATF, DNMT1, LIN9, LMNA, SUV420H1, SUV420H2, PELP1 and TMPO-alpha. May interact with NDC80. Interacts with GRIP1 and UBR4. Interacts with ARID4A and KDM5B. Interacts with E4F1 and LIMD1. Interacts with SMARCA4/BRG1 AND HDAC1. Interacts with adenovirus E1A protein, HPV E7 protein and SV40 large T antigen. Interacts with PSMA3 and USP4. Interacts (when methylated at Lys-860) with L3MBTL1.
Subcellular Location : Nucleus.
Tissue Specificity : Expressed in the retina.
Post-translational modifications : Phosphorylated by CDK6 and CDK4, and subsequently by CDK2 at Ser-567 in G1, thereby releasing E2F1 which is then able to activate cell growth. Dephosphorylated at the late M phase. SV40 large T antigen, HPV E7 and adenovirus E1A bind to the underphosphorylated, active form of pRb. Phosphorylation at Thr-821 and Thr-826 promotes interaction between the C-terminal domain C and the Pocket domain, and thereby inhibits interactions with heterodimeric E2F/DP transcription factor complexes. Dephosphorylated at Ser-795 by calcineruin upon calcium stimulation. CDK3/cyclin-C-mediated phosphorylation at Ser-807 and Ser-811 is required for G0-G1 transition. Phosphorylated by CDK1 and CDK2 upon TGFB1-mediated apoptosis.
N-terminus is methylated by METTL11A/NTM1. Monomethylated at Lys-860 by SMYD2, promoting interaction with L3MBTL1.
DISEASE : Defects in RB1 are the cause of childhood cancer retinoblastoma (RB) [MIM:180200]. RB is a congenital malignant tumor that arises from the nuclear layers of the retina. It occurs in about 1:20'000 live births and represents about 2% of childhood malignancies. It is bilateral in about 30% of cases. Although most RB appear sporadically, about 20% are transmitted as an autosomal dominant trait with incomplete penetrance. The 磷酸化视网膜母细胞瘤相关蛋白1抗体图片iagnosis is usually made before the age of 2 years when strabismus or a gray to yellow reflex from pupil ('cat eye') is investigated. 
Defects in RB1 are a cause of susceptibility to bladder cancer (BLC) [MIM:109800]. A malignancy originating in tissues of the urinary bladder. It often presents with multiple tumors appearing at different times and at different sites in the bladder. Most bladder cancers are transitional cell carcinomas. They begin in cells that normally make up the inner lining of the bladder. Other types of bladder cancer include squamous cell carcinoma (cancer that begins in thin, flat cells) and adenocarcinoma (cancer that begins in cells that make and release mucus and other fluids). Bladder cancer is a complex disorder with both genetic and environmental influences. 
Defects in RB1 are a cause of osteogenic sarcoma (OSRC) [MIM:259500].
Similarity : Belongs to the retinoblastoma protein (RB) family.

  磷酸化视网膜母细胞瘤相关蛋白1抗体图片储存温度：
 存在于血清、组织培养上清液或腹水中的抗体在-20℃下能够长期储存。低温存放不会损伤抗体活性。抗体的工作液通常储存于4℃中。此温度下，抗体的活性能稳定数月至数年亦不损失。抗体溶液不应反复冻融，因为反复冻融将导致部分抗体失活并产生不需要的蛋白—蛋白凝聚物。抗体的凝聚能导致活性丧失。这是由于抗原结合位点的空间构象被破坏，或由于产生的不溶物被离心或过滤而除去。冷凝蛋白类的抗体不能存放于4℃。因为在4℃下此类抗体会发生沉淀。一些鼠源性IgG3亚类的抗体有此特性。如果抗体在4℃下发生沉淀，就应该存放于室温下的叠氮钠溶液中。
 磷酸化视网膜母细胞瘤相关蛋白1抗体图片的分类：
按作用对象，可将其分为抗毒素、抗菌抗体、抗病毒抗体和亲细胞抗体（能与细胞结合的免疫球蛋白，如1型变态反应中的lgE反应素抗体，能吸附在靶细胞膜上）；按理化性质和生物学功能，可将其分为IgM、IgG、IgA、IgE、IgD五类；按抗体的来源，可 将其分为天然抗体和免疫抗体。抗体就是免疫球蛋白，是改变了的球蛋白分子。由特异性抗原刺激产生，抗体的产生是由于抗原侵入人体后引起各种免疫细胞相互作用，使淋巴细胞中的B细胞分化增殖而形成浆细胞，浆细胞可产生分泌抗体。

磷酸化视网膜母细胞瘤相关蛋白1抗体图片按理化性质和生物学功能，可将其分为IgM、IgG、IgA、IgE、IgD五类。
IgM抗体是免疫应答中首先分泌的抗体。它们在与抗原结合后启动补体的级联反应。它们还把入侵者相互连接起来，聚成一堆便于巨噬细胞的吞噬；
IgG抗体激活补体，中和多种毒素。IgG持续的时间长，是 唯一能在母亲妊娠期穿过胎盘保护胎儿的抗体。他们还从乳腺分泌进入初乳，使新生儿得 到保护；
IgA抗体进入身体的黏 膜表面，包括呼吸、消化、生殖等管道的黏膜，中和感染因子。还可以通过母乳的初乳把这种抗体输送到新生儿的消化道黏膜中，是在母乳中含量最多，最为重要的一类抗体；
IgE抗体的尾部与嗜碱细胞、肥大细胞的细胞膜结合。当抗体与抗原结合后，嗜碱细胞与肥大细胞释放组织胺一类物质促进炎症的发展。这也是引发速发型过敏反应的抗体；
IgD抗体的作用还不太清楚。它们主要出现在成熟的B淋巴细胞表面上，可能与B细胞的分化有关。（IgD于1995年从人骨髓瘤蛋白中发现，分子量为175kD，主要由扁桃体、脾等处浆细胞产生，人血清中IgD浓度为3～40μg/ml,不到血清总Ig的1%，在个体发育中合成较晚。IgD铰链区很长，且对蛋白酶水解敏感，因此IgD半衰期很短，仅2.8天。血清中IgD确切的免疫功能尚不清楚。在B细胞分化到成熟B细胞阶段，除了表达SmIgD，抗原刺激后表现为免疫耐受。成熟B细胞活化后或者活化后或者变成记忆B细胞时，SmIgD逐渐消失。
