Summary: Predicted to enable ephrin receptor binding activity. Involved in negative regulation of axonogenesis and trans-synaptic signaling by trans-synaptic complex, modulating synaptic transmission. Acts upstream of or within T cell costimulation; adult walking behavior; and axon choice point recognition. Is active in glutamatergic synapse; hippocampal mossy fiber to CA3 synapse; and presynaptic membrane. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; integumental system; and sensory organ. Used to study movement disease. Orthologous to human EFNB3 (ephrin B3). [provided by Alliance of Genome Resources, Dec 2024]

Ephrin B3 exacerbates colitis and colitis-associated colorectal cancer.
Title: Ephrin B3 exacerbates colitis and colitis-associated colorectal cancer.
EphA2 mAb treatment could partially inhibit LPSinduced inactivation of EphBEphrin B3 signalling, while Ephrin B3 overexpression could abrogate LPSinduced activation of EphA2Ephrin A1 signalling. EphB1/Ephrin B3 signalling may antagonise the EphA2/Ephrin A1dependent pathway following LPS treatment
Title: Eph/ephrin signalling serves a bidirectional role in lipopolysaccharide‑induced intestinal injury.
Data suggest that molecules in the erythropoietin-producing hepatocellular receptor B family (EPHB) / ephrinB (EFNB) signalling pathways, specifically ephrin B3 and GRIP1, are involved blood pressure regulation.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
