Application Notes
In WB a band can be seen at approx. 50 kDa, representing the OXPAT protein.
In Simple Western only 10 - 15 uL of the recommended dilution is used per data point. Separated by Size-Wes, Sally Sue/Peggy Sue. The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.
Theoretical MW
50 kDa. Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background
OXPAT (PLIN5/Perilipin 5) is a novel PAT-1 (Perilipin, ADRP and TIP47) that binds to lipid droplets (LDs) and protects them from lipolytic degradation. The tissue distribution of PAT-1 proteins differs considerably, however, all of them are involved in accumulation and metabolism of lipids in LDs. OXPAT covers LDs in the cytosol and its expression is highest in tissues with a high fat-oxidative capacity, such as heart, oxidative (type I) skeletal muscles and brown adipose tissue wherein the OXPAT contents parallel the LD content. OXPAT overexpression in OP-9 and COS-7 cells increased cellular triglyceride storage in parallel with increases in fatty acid oxidation and induction of gene expression of mitochondrial enzymes involved in oxidative metabolism. OXPAT has the potential of modulating the interaction of the major triacylglycerol lipase ATGL with LD as well as with its co-factor CGI-58 in a well control manner to regulate LD lipolysis. OXPAT expression is up-regulated by PPARalpha, and this regulation appears to be part of an expression program that shifts the metabolism of cells from fatty acid storage to oxidation.

OXPAT: Regulating Lipid Metabolism during Dietary Fluctuations OXPAT is the mammalian form of the PAT (perilipin, adipophilin, and TIP47) gene family that consists of proteins associated with lipid droplets (LDs) in fat-storing adipocyte cells. They serve to protect LDs from natural lipases responsible for breaki... Read full blog post.
