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, Oct 2024]

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.
