    2. TPTE2 was originally reported to be a phosphoinositide 3'-phosphatase, like the tumor suppressor PTEN. Later on, other homologous phosphatases, such as Ci-VSP and Dr-VSP, have been described. These proteins are 5'-phosphatases. More recently, using a chimeric construct, we have shown that the catalytic domain of TPTE2 behaves as a 5'-phosphatase as well.

    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 (4) includes an additional exon in the 5' UTR and lacks three consecutive in-frame exons in the coding region, compared to variant 3. The resulting isoform (delta) has the same N- and C-termini but lacks an internal segment compared to isoform gamma.

      Status: VALIDATED

      Description
      Transcript Variant: This variant (5) lacks multiple 5' exons but has an alternate segment at the 5' end compared to variant 3. These differences cause translation initiation at a downstream AUG and the resulting isoform (C2) has a much shorter N-terminus, compared to isoform gamma.

      Description
      Transcript Variant: This variant (6) contains three alternate 5' exons and has an additonal exon in the 3' region, which includes a stop codon, compared to variant 3. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 3, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
