    Summary
    Predicted to enable cargo adaptor activity. Predicted to act upstream of or within intracellular protein transport and vesicle-mediated transport. Predicted to be located in trans-Golgi network. Predicted to be part of AP-4 adaptor complex. Is expressed in several structures, including alimentary system; brain; eye; genitourinary system; and hemolymphoid system. Human ortholog(s) of this gene implicated in hereditary spastic paraplegia 51 and stuttering. Orthologous to human AP4E1 (adaptor related protein complex 4 subunit epsilon 1).

    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.
