    Summary
    Predicted to enable ephrin receptor binding activity and guanyl-nucleotide exchange factor activity. Predicted to be involved in several processes, including activation of GTPase activity; ephrin receptor signaling pathway; and negative regulation of dendritic spine morphogenesis. Predicted to be located in cytoplasm; growth cone; and membrane. Predicted to be active in glutamatergic synapse. Orthologous to human NGEF (neuronal guanine nucleotide exchange factor).

    Expression
    Biased expression in Brain (RPKM 231.3), Uterus (RPKM 56.0) and 3 other tissues See more

    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.
