蛋白别名
蛋白介绍
Chromatin binding factor that binds to DNA sequence specific sites. Involved in transcriptional regulation by binding to chromatin insulators and preventing interaction between promoter and nearby enhancers and silencers. Acts as transcriptional repressor binding to promoters of vertebrate MYC gene and BAG1 gene. Also binds to the PLK and PIM1 promoters. Acts as a transcriptional activator of APP. Regulates APOA1/C3/A4/A5 gene cluster and controls MHC class II gene expression. Plays an essential role in oocyte and preimplantation embryo development by activating or repressing transcription. Seems to act as tumor suppressor. Plays a critical role in the epigenetic regulation. Participates in the allele-specific gene expression at the imprinted IGF2/H19 gene locus. On the maternal allele, binding within the H19 imprinting control region (ICR) mediates maternally inherited higher-order chromatin conformation to restrict enhancer access to IGF2. Plays a critical role in gene silencing over considerable distances in the genome. Preferentially interacts with unmethylated DNA, preventing spreading of CpG methylation and maintaining methylation-free zones. Inversely, binding to target sites is prevented by CpG methylation. Plays a important role in chromatin remodeling. Can dimerize when it is bound to different DNA sequences, mediating long-range chromatin looping. Mediates interchromosomal association between IGF2/H19 and WSB1/NF1 and may direct distant DNA segments to a common transcription factory. Causes local loss of histone acetylation and gain of histone methylation in the beta-globin locus, without affecting transcription. When bound to chromatin, it provides an anchor point for nucleosomes positioning. Seems to be essential for homologous X-chromosome pairing. May participate with Tsix in establishing a regulatable epigenetic switch for X chromosome inactivation. May play a role in preventing the propagation of stable methylation at the escape genes from X- inactivation. Involved in sister chromatid cohesion. Associates with both centromeres and chromosomal arms during metaphase and required for cohesin localization to CTCF sites. Regulates asynchronous replication of IGF2/H19.

在免疫反应方面，基于抗原的刺激在体内形成、并与抗原作特异性结合的蛋白质之总称。其化学实质是免疫球蛋白。抗体，按照抗原抗体反应的类型可分别称为沉淀素、凝集素、溶血素、溶菌素、抗毒素、中和抗体等，但这些并不等于有相应的不同抗体存在，一般多只表明抗体反应的多样性而已。抗体在血清中含量最多（体液抗体=humoral antibody）；含有某特定抗体的血清称为抗血或免疫血清。
机体在抗原物质刺激下，由B细胞分化成的浆细胞所产生的、可与相应抗原发生特异性结合反应的免疫球蛋白。因为最初有人用电泳证明血清中抗体活性在γ球蛋白部分，故曾把抗体统称为两种（γ）球蛋白。后来证明，抗体并不都在γ区；而且位于γ区的球蛋白，也不一定都具有抗体活性。1964年，世界卫生组织举行专门会议，将具有抗体活性以及与抗体相关的球蛋白统称为免疫球蛋白（Ig）。如骨髓瘤蛋白，巨球蛋白血症、冷球蛋白血症等患者血清中存在的异常免疫球蛋白以及“正常人”天然存在的免疫
