    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]

    GeneRIFs: Gene References Into Functions

    What's a GeneRIF?
    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.
      Title: MiR-4319 suppresses colorectal cancer progression by targeting ABTB1.
    2. BPOZ-2 promoted eEF1A1 ubiquitylation and degradation, suggesting that eEF1A1 is a substrate of BPOZ-2.
      Title: BPOZ-2 directly binds to eEF1A1 to promote eEF1A1 ubiquitylation and degradation and prevent translation.
    3. Study showed that BPOZ-2 is a human counterpart of yeast Btb3p, which is a putative adaptor for Pcu3p-based ubiquitin ligase; BPOZ-2 bound to E3 ligase CUL3 in vitro and in vivo.
      Title: Bood POZ containing gene type 2 is a human counterpart of yeast Btb3p and promotes the degradation of terminal deoxynucleotidyltransferase.

    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.

      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).
