We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody. Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.

Supplementary information

Ephrin A1 also known as EFNA1 is a membrane-bound ligand that belongs to the ephrin family of proteins. It has a mass of approximately 22 kDa. Ephrin A1 engages in the binding and activation of Eph receptors particularly EphA2 which mediates bidirectional signaling between cells. This protein is widely expressed in various tissues including the adult brain lungs and liver. It plays a significant role in cell-cell communication especially during developmental processes.

Biological function summary

Ephrin A1 contributes to the regulation of cell movement and adhesion. It often forms part of a receptor-ligand complex with Eph receptors on adjacent cells. This interaction controls the guidance of axonal growth angiogenesis and tissue boundary formation. In the nervous system ephrin A1 influences the segregation of synaptic connections playing a role in developing the proper neural circuitry. Its expression patterns suggest its involvement in vascular processes and other critical physiological functions.

Pathways

Ephrin A1 is significantly involved in various signaling pathways that mediate cellular attachment and repulsion features. Notably it participates in the Eph/ephrin signaling and the Rho family GTPase signaling pathways. Through its interaction with the EphA2 receptor ephrin A1 regulates cytoskeletal dynamics and influences both integrin-mediated adhesion and cell migration. These pathways are important for maintaining cellular architecture and orchestrating cellular responses to environmental cues.

Ephrin A1 has been implicated in several pathological conditions notably breast cancer and glioblastoma. It interacts with the EphA2 receptor which is overexpressed in these cancers contributing to tumor development and progression. It is also associated with cancer-related proteins involved in metastatic signaling. Studies show that disrupted ephrin A1/EphA2 interactions can affect tumor angiogenesis and cellular proliferation highlighting its potential as a target for therapeutic intervention in cancer biology.

Target data

Cell surface GPI-bound ligand for Eph receptors, a family of receptor tyrosine kinases which are crucial for migration, repulsion and adhesion during neuronal, vascular and epithelial development. Binds promiscuously Eph receptors residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells (PubMed : 17332925, PubMed : 18794797). Involved in angiogenesis, regulating vascular endothelial cell differentiation and migration through activation of EPHA2. Acts as a ligand for EPHA3, inhibiting epithelial-to-mesenchymal transition of cardiac cells and playing a role in heart development (PubMed : 12794130). May also contribute to dendritic spine morphogenesis (By similarity).
