Summary
This gene encodes a protein with an ankyrin repeat region and two BTB/POZ domains, which are thought to be involved in protein-protein interactions. Expression of this gene is activated by the phosphatase and tensin homolog, a tumor suppressor. Alternate splicing results in three transcript variants. [provided by RefSeq, Mar 2010]

  1. Study demonstrates that miR-4319 is expressed at a low level in colorectal cancer (CRC) tissues, which predicts the poor clinical outcome of CRC. MiR-4319 regulates the proliferation, cell cycle, invasion and migration of CRC cells. Mechanically, miR-4319 is found to be transcriptionally regulated by PLZF, and acts as a tumour suppressor in CRC by targeting ABTB1.

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: REVIEWED

    Description
    Transcript Variant: This variant (3, also known as BPOZ type 3) uses an alternate splice site in an internal exon, compared to variant 2. This variant is represented as non-coding because the use of the 5'-most supported translational start codon, as used in variant 2, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
