    Summary
    Predicted to enable adenyl-nucleotide exchange factor activity and identical protein binding activity. Predicted to be involved in protein transport. Located in endoplasmic reticulum. Is expressed in brain; chondrocranium; eye; pancreas; and testis. Human ortholog(s) of this gene implicated in primary cerebellar degeneration. Orthologous to human SIL1 (SIL1 nucleotide exchange factor). [provided by Alliance of Genome Resources, Nov 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.
