NTF4 激活 NTRK2(TRKB)信号
中文名称
通路描述
神经生长因子受体酪氨酸激酶 NTRK2(TRKB)的信号可以通过与神经生长因子-4(NTF4,也称为 NT-4)结合而被激活,NTF4 作为 NTRK2 的配体(Klein 等,1992;Ip 等,1993;Ohira 等,2001)。与 NTF4 结合触发 NTRK2 二聚化(Ohira 等,2001),并导致 NTRK2 二聚体在受体细胞质尾部的保守酪氨酸残基上发生磷酸化(Minichiello 等,1998)。磷酸化的酪氨酸残基随后作为结合位点,招募触发下游信号级联反应的效应蛋白。
英文描述
NTF4 activates NTRK2 (TRKB) signaling Signaling by the neurotrophin receptor tyrosine kinase NTRK2 (TRKB) can be activated by binding to neurotrophin-4 (NTF4, also known as NT-4), which functions as a ligand for NTRK2 (Klein et al. 1992, Ip et al. 1993, Ohira et al. 2001). Binding to NTF4 triggers NTRK2 dimerization (Ohira et al. 2001) and trans-autophosphorylation of NTRK2 dimers on conserved tyrosine residues in the cytoplasmic tail of the receptor (Minichiello et al. 1998). Phosphorylated tyrosine residues subsequently serve as docking sites for recruitment of effector proteins that trigger downstream signaling cascades.
