/功能
Transcription factor that is involved in embryonic development, establishment of tissue-specific gene expression and regulation of gene expression in differentiated tissues. Is thought to act as a 'pioneer' factor opening the compacted chromatin for other proteins through interactions with nucleosomal core histones and thereby replacing linker histones at target enhancer and/or promoter sites. Binds DNA with the consensus sequence 5'-[AC]A[AT]T[AG]TT[GT][AG][CT]T[CT]-3' . In embryonic development is required for notochord formation. Involved in the development of multiple endoderm-derived organ systems such as the liver, pancreas and lungs; FOXA1 and FOXA2 seem to have at least in part redundant roles. Originally discribed as a transcription activator for a number of liver genes such as AFP, albumin, tyrosine aminotransferase, PEPCK, etc. Interacts with the cis-acting regulatory regions of these genes. Involved in glucose homeostasis; regulates the expression of genes important for glucose sensing in pancreatic beta-cells and glucose homeostasis. Involved in regulation of fat metabolism. Binds to fibrinogen beta promoter and is involved in IL6-induced fibrinogen beta transcriptional activation.Wolfrum C., Besser D., Luca E., Stoffel M. Proc. Natl. Acad. Sci.

文献和实验在免疫反应方面,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
指仅对一种抗原决定基的纯粹的抗体。这类抗体不可能通过将抗原 胞的 Hybridoma,在试管内制成了纯粹的单克隆抗体。用某种抗原使动物产生免疫感应,对应于抗原之不同部分可制成各种不同的抗体复合体。然而,因为一个产生抗体的细胞,只能产生一种抗体,所以骨髓肿瘤细胞与产生抗体细胞间的细胞杂种,可形成边产生抗体边增殖的 hybridoma,将每个杂种细胞进行克隆(无性繁殖系)培养,则一个克隆的细胞群只由单种类产生同一抗体的细胞所组成,这样得到的就是单克隆抗体。此抗体在测定
