  • Function

    Plays important roles in controlling the metabolism of fatty acids at differents levels. Acts as a magnesium-dependent phosphatidate phosphatase enzyme which catalyzes the conversion of phosphatidic acid to diacylglycerol during triglyceride, phosphatidylcholine and phosphatidylethanolamine biosynthesis in the reticulum endoplasmic membrane. Acts also as a nuclear transcriptional coactivator for PPARGC1A/PPARA to modulate lipid metabolism gene expression (By similarity). Is involved in adipocyte differentiation. May also be involved in mitochondrial fission by converting phosphatidic acid to diacylglycerol.
  • Tissue specificity

    Abundant in adipose tissue and skeletal muscle. Lower levels in some portions of the digestive tract.
  • Involvement in disease

    Defects in LPIN1 are a cause of autosomal recessive acute recurrent myoglobinuria (ARARM) [MIM:268200]; also known as acute recurrent rhabdomyolysis. Recurrent myoglobinuria is characterized by recurrent attacks of rhabdomyolysis (necrosis or disintegration of skeletal muscle) associated with muscle pain and weakness and followed by excretion of myoglobin in the urine. Renal failure may occasionally occur. Onset is usually in early childhood under the age of 5 years.
  • Sequence similarities

    Belongs to the lipin family.
  • Domain

    Contains one Leu-Xaa-Xaa-Ile-Leu (LXXIL), a transcriptional binding motif, which mediates interaction with PPARA.
    Contains 1 Asp-Xaa-Asp-Xaa-Thr (DXDXT) motif, a catalytic motif essential for phosphatidate phosphatase activity.
  • Post-translational

    Phosphorylated at multiple sites in response to insulin. Phosphorylation is controlled by the mTOR signaling pathway (By similarity). Dephosphorylated in response to epinephrine and oleic acid.
  • Cellular localization

    Nucleus. Cytoplasm > cytosol. Endoplasmic reticulum membrane.

  • ab92316 at a 1/50 dilution, staining Lipin 1 in paraffin-embedded Human colon tissue.

    Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.

  • ab92316 at a 1/50 dilution, staining Lipin 1 in paraffin-embedded Human uterus tissue.

    Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.

  • Immunofluorescent staining of HepG2 cells using ab92316 at 1/100 dilution.
  • Overlay histogram showing HepG2 cells stained with ab92316 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab92316, 1/100 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

Customer reviews and Q&As


Thank you for contacting us and your interest in our products.

We have used the Anti-Lipin 1 antibody [EPR3725] (ab92316) in the staining of paraffin-embedded Human colon and uterus tissue. We have not as yet used the antibody to stain liver tissue and I cannot therefore share any images of staining in liver.

I have however had a look to see where lipin 1 might be expected to be expressed in liver tissue and came across the following references which may be of help to you:




I hope this information has been of help. If you have any further information, please do not hesitate to ask.
