/功能
Tyrosine-protein kinase that acts as a cell-surface receptor for VEGFC and VEGFD, and plays an essential role in adult lymphangiogenesis and in the development of the vascular network and the cardiovascular system during embryonic development. Promotes proliferation, survival and migration of endothelial cells, and regulates angiogenic sprouting. Signaling by activated FLT4 leads to enhanced production of VEGFC, and to a lesser degree VEGFA, thereby creating a positive feedback loop that enhances FLT4 signaling. Modulates KDR signaling by forming heterodimers. The secreted isoform 3 may function as a decoy receptor for VEGFC and/or VEGFD and play an important role as a negative regulator of VEGFC-mediated lymphangiogenesis and angiogenesis. Binding of vascular growth factors to isoform 1 or isoform 2 leads to the activation of several signaling cascades; isoform 2 seems to be less efficient in signal transduction, because it has a truncated C-terminus and therefore lacks several phosphorylation sites. Mediates activation of the MAPK1/ERK2, MAPK3/ERK1 signaling pathway, of MAPK8 and the JUN signaling pathway, and of the AKT1 signaling pathway. Phosphorylates SHC1. Mediates phosphorylation of PIK3R1, the regulatory subunit of phosphatidylinositol 3-kinase. Promotes phosphorylation of MAPK8 at 'Thr-183' and 'Tyr-185', and of AKT1 at 'Ser-473'.

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
