    Summary
    This gene encodes a member of the sorting nexin family. Members of this family contain a phox (PX) domain, which is a phosphoinositide binding domain, and are involved in intracellular trafficking. This protein does not contain a coiled coil region, like some family members, but contains a SH3 domain. Multiple transcript variants encoding different isoforms have been found for this gene.

    What's a GeneRIF?
    1. We propose a model where upon autophagy induction, SNX18 recruits Dynamin-2 to induce budding of ATG9A and ATG16L1 containing membranes from recycling endosomes that traffic to sites of autophagosome formation.
      Title: SNX18 regulates ATG9A trafficking from recycling endosomes by recruiting Dynamin-2.
    2. SNX18 promotes autophagosome formation by virtue of its ability to remodel membranes and provide membrane to forming autophagosomes.
      Title: Membrane remodeling by the PX-BAR protein SNX18 promotes autophagosome formation.
    3. The sorting nexin 9 (SNX9) subfamily members - SNX9, SNX18 and SNX33 - are required for progression and completion of mitosis.

      Title: SNX18 shares a redundant role with SNX9 and modulates endocytic trafficking at the plasma membrane.
    6. The results indicate that SNX9-family members make up discrete membrane-scission units together with dynamin, and suggest that SNX18 mediates budding of carriers for AP-1-positive endosomal trafficking.

    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.
