    Summary
    Enables ephrin receptor binding activity. Involved in ephrin receptor signaling pathway; negative regulation of dendritic spine morphogenesis; and regulation of synapse pruning. Is active in glutamatergic synapse. Is expressed in several structures, including brain; chondrocranium; genitourinary system; heart valve; and liver. Orthologous to human NGEF (neuronal guanine nucleotide exchange factor). [provided by Alliance of Genome Resources, Dec 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.

      Description
      Transcript Variant: This variant (2) contains a different segment for its 5' UTR and 5' coding region, and lacks other coding region exons, compared to variant 1. The resulting protein (isoform 2) has a shorter and distinct N-terminus when it is compared to isoform 1.
