EFNA1 / EphrinA1 Protein QC Testing

純度: > 95 % as determined by SDS-PAGE SDS-PAGE
內(nèi)**: < 1.0 EU per μg of the protein as determined by the LAL method
穩(wěn)定性: Samples are stable for up to twelve months from date of receipt at -70℃
預(yù)測(cè)N端: Ala 18

EFNA1 / EphrinA1蛋白背景綜述

The ephrins (Eph) and Eph receptors comprise the largest subfamily of receptor protein-tyrosine kinases and have been implicated in mediating developmental events, especially in the nervous system and in erythropoiesis. Based on their structures and sequence relationships, ephrins are divided into the ephrin-A (EFNA) class, which are anchored to the membrane by a glycosylphosphatidylinositol linkage, and the ephrin-B (EFNB) class, which are transmembrane proteins. All ephrins share a conserved extracellular sequence, which most likely corresponds to the receptor-binding domain. In?molecular biology , ephrins and Eph receptors are components of cell signaling pathways involved in animal development, and implicated in some cancers. Eph receptors are classified as receptor tyrosine kinases (RTKs), and form the largest sub-family of RTKs. Almost all Eph receptors are expressed during various well defined stages of development in assorted locations and concentrations. Ephrin-A1, also known as B61, LERK-1, and EFL-1, is a member of the ephrin ligand family which binds members of the Eph receptor family. Ephrin-A1 has been shown to bind EphA1, EphA2, EphA3, EphA4, EphA5, EphA6, EphA7, and EphB1. The extracellular domains of human and mouse ephrin-A1 share 85% amino acid identity.
