    Summary
    The protein encoded by this gene can bind GOLPH3, linking the Golgi to the cytoskeleton and influencing Golgi membrane trafficking. The encoded protein is also part of a complex that assembles lamellar actomyosin bundles and may be required for cell migration. [provided by RefSeq, Oct 2016]
    Annotation information
    Note: This gene is now merged into MYO18A (GeneID:399687) due to overlap of a significant portion of the transcript with 3' terminal exon of MYO18A. [10 Jan 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.

      Transcript Variant: This variant (6) lacks an alternate in-frame exon and represents use of an alternate promoter, therefore differing in the 5' UTR and 5' coding sequence, compared to variant 3. These differences cause translation initiation at a downstream start codon and result in an isoform (f) that lacks an alternate internal segment and has a shorter N-terminus, compared to isoform c.
