过氧化物酶体增殖物激活受体γ辅激活子1α/β重组兔单抗

PPARGC1A

Peroxisome proliferator-activated receptor gamma coactivator 1-alpha

Binds MYBBP1A, which inhibits transcriptional activation by this protein. Interacts with PRDM16. Interacts with LRPPRC. Homooligomer. Interacts with LPIN1.

Nucleus.

Heart, skeletal muscle, liver and kidney. Expressed at lower levels in brain and pancreas and at very low levels in the intestine and white adipose tissue. In skeletal muscle, levels were lower in obese than in lean subjects and fasting induced a 2-fold increase in levels in the skeletal muscle in obese subjects.

hosphorylation by AMPK in skeletal muscle increases activation of its own promoter. Phosphorylated by CLK2.
Heavily acetylated by GCN5 and biologically inactive under conditions of high nutrients. Deacetylated by SIRT1 in low nutrients/high NAD conditions.

Contains 1 RRM (RNA recognition motif) domain.

Transcriptional coactivator for steroid receptors and nuclear receptors. Greatly increases the transcriptional activity of PPARG and thyroid hormone receptor on the uncoupling protein promoter. Can regulate key mitochondrial genes that contribute to the program of adaptive thermogenesis. Plays an essential role in metabolic reprogramming in response to dietary availability through coordination of the expression of a wide array of genes involved in glucose and fatty acid metabolism.
