Genes affected
PPT2-EGFL8 (HGNC:48343): (PPT2-EGFL8 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring PPT2 (palmitoyl-protein thioesterase 2) and EGFL8 (EGF-like-domain, multiple 8) genes located in the major histocompatibility complex class III region of chromosome 6. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Feb 2011]
AGPAT1 (HGNC:324): (1-acylglycerol-3-phosphate O-acyltransferase 1) This gene encodes an enzyme that converts lysophosphatidic acid (LPA) into phosphatidic acid (PA). LPA and PA are two phospholipids involved in signal transduction and in lipid biosynthesis in cells. This enzyme localizes to the endoplasmic reticulum. This gene is located in the class III region of the human major histocompatibility complex. Alternative splicing results in two transcript variants encoding the same protein.
