Summary: This gene was identified as a tumor suppressor that is mutated in a large number of cancers at high frequency. The protein encoded by this gene is a phosphatidylinositol-3,4,5-trisphosphate 3-phosphatase. It contains a tensin like domain as well as a catalytic domain similar to that of the dual specificity protein tyrosine phosphatases. Unlike most of the protein tyrosine phosphatases, this protein preferentially dephosphorylates phosphoinositide substrates. It negatively regulates intracellular levels of phosphatidylinositol-3,4,5-trisphosphate in cells and functions as a tumor suppressor by negatively regulating AKT/PKB signaling pathway. The use of a non-canonical (CUG) upstream initiation site produces a longer isoform that initiates translation with a leucine, and is thought to be preferentially associated with the mitochondrial inner membrane. This longer isoform may help regulate energy metabolism in the mitochondria. A pseudogene of this gene is found on chromosome 9. Alternative splicing and the use of multiple translation start codons results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Feb 2015]

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 (1) encodes multiple isoforms due to the use of alternative translation initiation codons. The longest isoform (PTEN-L, PMID:23744781; also known as PTENalpha, PMID: 24768297) is derived from the use of an upstream non-AUG (CUG) start codon, while two shorter isoforms are derived from downstream AUG start codons. The most abundant isoform (PTEN), which is derived from the use of the 5'-most AUG start codon, is represented in this RefSeq.

See identical proteins and their annotated locations for NP_001291647.1

Status: REVIEWED

Description

Transcript Variant: This variant (2) both contains and lacks alternate exons in its 5' UTR compared to variant 1. This variant represents translation initiation at a downstream AUG compared to the more upstream CUG and AUG start codons, as used in variant 1. Use of the more 5' initiation codons, as used in variant 1, is associated with a truncated ORF that would render the transcript a candidate for nonsense-mediated decay (NMD). Leaky scanning may allow translation initiation at the downstream AUG to encode an isoform (3) that has a shorter N-terminus, compared to isoform PTENalpha and PTEN.
