**Background of EPHB1 Recombinant Protein**
EPHB1. a member of the Eph receptor tyrosine kinase family, plays critical roles in cell-cell communication during development and tissue homeostasis. Eph receptors are divided into EphA and EphB subclasses based on ligand specificity and sequence homology. EPHB1 binds preferentially to membrane-anchored ephrin-B ligands, initiating bidirectional signaling pathways that regulate cell adhesion, migration, and boundary formation. These interactions are vital in neural development, angiogenesis, and synaptic plasticity, as well as pathological processes such as cancer metastasis and neurodegenerative diseases.
Structurally, EPHB1 consists of an extracellular region with ligand-binding domains, a transmembrane segment, and an intracellular tyrosine kinase domain. Its activation via ephrin-B binding triggers receptor clustering, autophosphorylation, and downstream signaling cascades involving MAPK, PI3K/Akt, and Rho GTPases. Dysregulation of EPHB1 is linked to tumor progression, neurodevelopmental disorders, and impaired tissue repair.
Recombinant EPHB1 protein is engineered for *in vitro* and *in vivo* studies to dissect its biological functions and therapeutic potential. Produced using mammalian expression systems (e.g., HEK293 or CHO cells), it retains post-translational modifications necessary for ligand binding and activity. Applications include ligand-receptor interaction assays, drug screening, structural studies (e.g., X-ray crystallography), and functional analyses in disease models.
Research using EPHB1 recombinant protein has highlighted its dual role in cancer—acting as a tumor suppressor in colorectal cancer but promoting invasiveness in glioblastoma. Additionally, it shows promise in regenerative medicine by modulating axon guidance and stem cell differentiation. Continued exploration of EPHB1 signaling may yield targeted therapies for cancer and neurological disorders.
