酪氨酸激酶受体( tyrosine kinase receptor ) 相关知识点: 试题来源: 解析 酪氨酸激激酶受体:为膜上的一种特殊蛋白质,只有一个跨膜螺旋和一个较短的膜内肽段,当膜外的肽段同相应的化学信号结合时,可以直接激活膜内侧肽段的蛋白激活活性,由此再引发各种细胞内功能的改变。
One of the potential molecular pathways used by cancer cells as an alternative survival system to overcome the blockage of EGFR function is represented by the activation of other tyrosine kinase receptor systems which are not EGFR-related – for example, the insulin-like growth factor (IGF) ...
RTKs是最大的一类酶联受体,它既是受体,又是酶,能够同配体结合,并将靶蛋白的酪氨酸残基磷酸化。所有的RTKs都是由三个部分组成的:含有配体结合位点的细胞外结构域、单次跨膜的疏水α螺旋区、含有酪氨酸蛋白激酶(RTK)活性的细胞内结构域。 已发现50多种RTKs,主要的几种类型包括:①表皮生长因子受体;②血小板生长...
Biochemistry System-level studies of receptor tyrosine kinase signaling networks HARVARD UNIVERSITY Gavin MacBeath KrallJordan AsherReceptor tyrosine kinases are transmembrane proteins that activate intracellular signaling pathways in response to extracellular ligands. Upon activation, receptor tyrosine kinases ...
but might also interfere with ligand binding or affect receptor dimerization or the stimulation of the immune system. Kinase inhibitors are small drugs that block the enzymatic activity by competing with the ATP-binding site of tyrosine kinases. Furthermore, blocking the prevalent signal transduction...
[名词解释] 受体酪氨酸激酶(receptortyrosinekinase,RTK) 相关知识点: 试题来源: 解析 是细胞膜表面受体的一类,是一类胞质结构域具有蛋白酪氨酸激酶功能的细胞表面受体,这类受体本身兼具受体和酪氨酸激酶两种功能。当这类受体与配体结合后可催化自身或底物蛋白的酪氨酸残基磷酸化,激活后的蛋白质进一步催化细胞内的一...

Receptor tyrosine kinases (RTKs) are enzyme-linked cell-surface receptors (Figure 1). A kinase is an enzyme that transfers phosphate groups from ATP to another protein. RTKs transfers phosphate groups to tyrosine molecules (tyrosine residues). First, signaling molecules bind to the extracellular do...
