目标/特异性 | Phospho-Insulin Receptor (Tyr1345) (14A4) Rabbit mAb detects transfected levels of insulin receptor β only when phosphorylated at Tyr1345. The antibody slightly cross-reacts with activated IGF-I receptors and some other activated tyrosine kinases. |

背景 | Type I insulin-like growth factor receptor (IGF-IR) is a transmembrane receptor tyrosine kinase that is widely expressed in many cell lines and cell types within fetal and postnatal tissues (1-3). Receptor autophosphorylation follows binding of the IGF-I and IGF-II ligands. Three tyrosine residues within the kinase domain (Tyr1131, Tyr1135, and Tyr1136) are the earliest major autophosphorylation sites (4). Phosphorylation of these three tyrosine residues is necessary for kinase activation (5,6). Insulin receptors (IRs) share significant structural and functional similarity with IGF-I receptors, including the presence of an equivalent tyrosine cluster (Tyr1146/1150/1151) within the kinase domain activation loop. Tyrosine autophosphorylation of IRs is one of the earliest cellular responses to insulin stimulation (7). Autophosphorylation begins with phosphorylation of Tyr1146 and either Tyr1150 or Tyr1151, while full kinase activation requires triple tyrosine phosphorylation (8).I型胰岛素样生长因子受体(IGF-I)是一种跨膜受体酪氨酸激酶,广泛表达于许多细胞系,并在胎儿和产后组织细胞中表达(1-3)。受体与IGF-I和IGF-Ⅱ配体结合后发生自身磷酸化。激酶结构域的三个酪氨酸残基(Tyr1131,Tyr1135,Tyr1136)是最早确定的三个主要磷酸化位点(4)。三个酪氨酸残基的磷酸化对激酶的活化是必要的(5,6)。胰岛素受体(IR)与IGF-I受体有显著的结构和功能的相似性,都有激酶结构域激活环中对应的酪氨酸残基(Tyr1146/1150/1151)的存在。IR的酪氨酸磷酸化是胰岛素刺激最早的细胞反应之一(7)。自身磷酸化从Tyr1146和Tyr1150或Tyr1151的磷酸化开始,但完全的激酶活性需要三个酪氨酸残基的磷酸化(8)。 |
