Peroxisome proliferator-activated receptor gamma (PPAR-gamma or PPARG), also known as the glitazone receptor, or NR1C3 (nuclear receptor subfamily 1, group C, member 3) is a type II nuclear receptor that in humans is encoded by the PPARG gene.[1][2]

Contents

Function

PPARG regulates fatty acid storage and glucose metabolism. Many insulin sensitizing drugs used in the treatment of diabetes target PPARG as a means to lower serum glucose without increasing pancreatic insulin secretion. The genes activated by PPARG stimulate lipid uptake and adipogenesis by fat cells. PPARG knockout mice fail to generate adipose tissue when fed a high fat diet.[3]

This gene encodes a member of the peroxisome proliferator-activated receptor (PPAR) subfamily of nuclear receptors. PPARs form heterodimers with retinoid X receptors (RXRs) and these heterodimers regulate transcription of various genes. Three subtypes of PPARs are known: PPAR-alpha, PPAR-delta, and PPAR-gamma. The protein encoded by this gene is PPAR-gamma and is a regulator of adipocyte differentiation. Additionally, PPAR-gamma has been implicated in the pathology of numerous diseases including obesity, diabetes, atherosclerosis and cancer. Alternatively spliced transcript variants that encode different isoforms have been described.[4]

Interactions

Peroxisome proliferator-activated receptor gamma has been shown to interact with MED1,[5] PPARGC1A,[6][7] Nuclear receptor coactivator 3,[5] Retinoblastoma protein,[8] NCOA4,[9] EP300,[8][5] HDAC3,[10][8] Nuclear receptor coactivator 2,[5] EDF1,[11] Retinoid X receptor alpha[12][13][14] and Small heterodimer partner.[15]
