EphrinA3蛋白产品信息
产品名称：重组人 EphrinA3 / EFNA3 蛋白|EphrinA3 Protein|厂家价格|参数
EphrinA3 别名: EFNA3, EFL2, EPLG3, Ehk1-L, LERK3
表达方式: A DNA sequence encoding the human EphrinA3 (NP_004943.1) (Met 1- Ser 213 ) with the C-terminal propeptide removed was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.
种属: Human
表达宿主: Human Cells
EphrinA3蛋白质控指标
纯度: > 97%, as determined by SDS-PAGE SDS-PAGE:
内**: < 1.0 EU per 1μg of the protein as determined by the LAL method.
稳定性: Samples are stable for up to twelve months from date of receipt at -70℃
预测N端: Gln 23
分子量: The recombinant human EphrinA3/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer consists of 439 amino acids and has a predicted molecular mass of 49.5 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhEphrinA3/Fc monomer is approximately 60-65 kDa due to glycosylation.
缓冲液: Lyophilized from sterile PBS , pH 7.4
Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
Please contact us for any concerns or special requirements.

EphrinA3蛋白背景综述
The ephrins (EPH) and EPH-related receptors comprise the largest subfamily of receptor protein-tyrosine kinases (RTKs), and have been involved in a variety of biological processes, especially in the nervous system and in erythropoiesis, such as axon guidance and topographic map formation, synaptic plasticity, angiogenesis, and meanwhile have possible contributions to tumor growth and metastasis. Based on their structures and sequence relationships, ephrins are divided into the ephrin-A (EFNA) class which are anchored to the membrane by a GPI linkage, and the ephrin-B (EFNB) class, which are transmembrane proteins. 14 receptors and 8 ligands have been reported in mammals, and EphrinA3 is capable of binding EphA2, EphA3, EphA4, EphA5, EphA6, EphA7, EphA8, and EphB1. The EphrinA3 ligand may interact with the EphA5 receptor to restrict entorhinal axon terminals in the outer molecular layer of the dentate gyrus. Furthermore, Research evidences indicated that ephrin-A3, but not other ligands, binds to heparan sulfate, and the presence of cell surface heparan sulfate is required for the full biological activity of ephrin-A3.
