ef-1-a-1

eukaryotic translation elongation factor 1 alpha 1 (EEF1A1) encodes an isoform of the alpha subunit of the elongation factor-1 complex, which is responsible for the enzymatic delivery of aminoacyl tRNAs to the ribosome. This isoform (alpha 1) is expressed

eukaryotic translation elongation factor 1 alpha 1 (EEF1A1) (387-394) [Multiple species](TFA) 是延伸因子 1 亚基。真核翻译延伸因子 1 alpha 1 (EEF1A1) 编码延伸因子 alpha 亚基的同种型- 1 复合物，负责将氨酰 tRNA 酶促递送至核糖体。这种亚型（α 1）在脑、胎盘、肺、肝、肾和胰腺中表达，另一种亚型（α 2）在脑、心脏和骨骼肌中表达。这种亚型在 66% 的 Felty 综合征患者中被鉴定为自身抗原。已发现该基因在许多染色体上具有多个拷贝，其中一些（如果不是全部）代表不同的假基因。

ABO acts as an annexin A7 modulator, specifically binding to Thr286 to inhibit its phosphorylation on threonine (not on serine or tyrosine) residues within human umbilical vein endothelial cells (HUVECs). This compound furthers the annexin A7 interaction with the EF-hand protein GCA, leading to reduced GCA phosphorylation, lowered intracellular calcium levels, and enhanced autophagy in COS-7 cells. Moreover, ABO lessens phosphorylation of the microtubule-associated protein 1 light chain (LC3) in HUVECs and impedes the upregulation of phosphatidylcholine-specific phospholipase C (PC-PLC) due to oxidized low-density lipoprotein in vascular endothelial cells (VECs). In animal models, specifically apoE-/- mice on a Western diet, administration of ABO (50 or 100 mg/kg per day) has been shown to decrease PC-PLC expression, promote autophagy, and reduce apoptosis, lipid accumulation, and the extent of atherosclerotic plaques in the aortic endothelium.
