Summary: Proteins belonging to the phospholipase A2 (PLA2) family hydrolyze phospholipids into sn2 fatty acids and lysophospholipids. They function in a variety of cellular processes, including the digestion of phospholipids and the production of molecules that induce inflammatory responses. This gene encodes a member of the group II class of secretory PLA2s. The secreted enzyme binds to heparin on the cell surface. Mutations in this gene increase the occurrence of intestinal polyps caused by a dominant mutation in the adenomatosis polyposis coli gene. A frameshift inactivates this gene product in some mouse strains including the strain of the reference genome, C57BL/6J, whereas a functional protein is produced in other strains.

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 (1, non-coding) represents the non-functional allele that is present in several strains, including the strain of the reference genome, C57BL/6J. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 1, coding, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).

The following Reference Sequences have been suppressed. Explain

NM_011108.1: Suppressed sequence

Description

NM_011108.1: This RefSeq was permanently suppressed because it contains a frame-shift, which results in premature translation termination, thus rendering the transcript susceptible to nonsense-mediated mRNA decay (NMD).
