Low-molecular-weight, calcium-dependent phospholipase A2 genes are linked and map to homologous chromosome regions in mouse and human

Genomics. 1996 Mar 15;32(3):328-33. doi: 10.1006/geno.1996.0126.

Abstract

The Group IIA phospholipase gene (PLA2G2A) protein coding regions exhibit significant homology with recently described Group IIC (PLA2G2C) and Group V (PLA2GV) genes. All three genes are present in many mammalian species and are expressed in a tissue-specific pattern. Here, we demonstrate in human that they are tightly linked and map to chromosome 1p34-p36.1. We also show that the homologous mouse loci are tightly linked (no observed recombination) on the distal part of chromosome 4, a region exhibiting synteny with human 1p34-p36. Unlike its rodent counterpart, human PLA2G2C appears to be a nonfunctional pseudogene.
