    Summary
    Predicted to enable MIT domain binding activity and identical protein binding activity. Acts upstream of or within positive regulation of collateral sprouting. Predicted to be located in several cellular components, including Flemming body; endoplasmic reticulum-Golgi intermediate compartment; and extracellular exosome. Predicted to colocalize with chromatin. Is expressed in nervous system; sensory organ; submandibular gland primordium; tooth; and vibrissa. Orthologous to human IST1 (IST1 factor associated with ESCRT-III). [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 (3) contains an alternate exon compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
