    Summary
    Predicted to enable CD4 receptor binding activity. Predicted to be located in intracellular membrane-bounded organelle. Predicted to be active in cytosol and trans-Golgi network transport vesicle. Is expressed in extraembryonic component; head mesenchyme; tongue; and vertebral axis musculature. Used to study Mast syndrome. Human ortholog(s) of this gene implicated in Mast syndrome and hereditary spastic paraplegia. Orthologous to human SPG21 (SPG21 abhydrolase domain containing, maspardin).

    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.
