Summary
This gene encodes a member of the ephrin (EPH) family. The ephrins and EPH-related receptors comprise the largest subfamily of receptor protein-tyrosine kinases and have been implicated in mediating developmental events, especially in the nervous system and in erythropoiesis. Based on their structures and sequence relationships, ephrins are divided into the ephrin-A (EFNA) class, which are anchored to the membrane by a glycosylphosphatidylinositol linkage, and the ephrin-B (EFNB) class, which are transmembrane proteins. This gene encodes an EFNA class ephrin. Three transcript variants that encode distinct proteins have been identified. [provided by RefSeq, Jul 2008]

NCBI Reference Sequences (RefSeq)

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.

    Status: REVIEWED

    Description
    Transcript Variant: This variant (2) uses an alternate splice site in the 3' coding region, compared to variant 1, that results in a downstream translation termination. It encodes isoform b which has a little longer and distinct C-terminus compared to isoform a.

    Status: REVIEWED

    Description
    Transcript Variant: This variant (3), also known as ephrin-A4 (s), uses an alternate splice site in the 3' coding region, compared to variant 1, that results in a downstream translation termination. It encodes isoform c which has a distinct and slightly shorter C-terminus compared to isoform a. Isoform c lacks a characteristic transmembrane domain and the GPI-signal sequence contained in isoform a. Isoform c is a secreted molecule.
