Summary
Involved in synaptic vesicle budding from endosome. Acts upstream of or within several processes, including adipose tissue development; fat cell differentiation; and visual learning. Predicted to be located in Golgi apparatus. Predicted to be part of membrane coat. Predicted to be active in intracellular membrane-bounded organelle. Is expressed in mesonephros and urinary system. Used to study syndromic X-linked intellectual disability 5. Human ortholog(s) of this gene implicated in syndromic X-linked intellectual disability 5. Orthologous to human AP1S2 (adaptor related protein complex 1 subunit sigma 2). [provided by Alliance of Genome Resources, Apr 2022]

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: VALIDATED

    Description
    Transcript Variant: This variant (2) lacks an exon and contains an alternate 3' terminal exon, resulting in a different 3' coding region and 3' UTR, compared to variant 1. The encoded isoform (2) is shorter than isoform 1 and has a distinct C-terminus.
