amino terminus meaning in English
氨基端
Examples
- Signal ( leaser ) sequence a hydrophobic sequence at the amino terminus of a polypeptide chain that targets it for secretion in bacterial or incorporation into the endoplasmic reticulum in eukaryotic cells
讯息（指挥）序列蛋白质末端的一段疏水性氨基酸，在细菌中引导蛋白质分泌或在真核细胞中将蛋白质并入内质网。 - Trka , the high affinity ngf receptor , contains an intracellular domain with tyrosine kinase activity and an extracellular domain with three tandem leucine - rich motifs flanked by two cysteine clusters in their amino termini and two immunoglobulin - like domains in the more membrane - proximal region
膜外域含有8个亮氨酸的重复区域，其前后分别串联着一组半胱氨酸残基，紧挨细胞膜的是两个c2 -型免疫球蛋白样区ig和ig ；膜内域为酪氨酸激酶催化活性区。 - It has been demonstrated that kvl . 2 , an isoform of delayed - rectifier potassium channel , is up - regulated in the ischemic neurons . besides , the activity of kvl . 2 is tyrosine phosphorylation dependent , phosphorylation of the tyrosine residue in the amino terminus of the channel by tyrosine kinases suppresses the channel current . therefore , we hypothesize that vegf could enhance the phosphorylation of kvl . 2 , which results in an inhibition of / k
在介导i _ k的钾通道家族中， kv1 . 2是其中的一个亚型，研究报道它在缺血神经元中的表达是增高的；此外，它的活性与其酪氨酸磷酸化水平相关，在其氨基末端的酪氨酸残基经酪氨酸激酶磷酸化后可显著降低其介导的电流的幅度。
