GRN (granulin) is a large cysteine rich glycoprotein, also called progranulin, which has a molecular weight of 88,000kDa. It is the largest member of granulin/epithelin family of growth factors. This family is characterized a unique double cysteine rich motif.
Synonyms: Anti-Granulins precursor; Anti-PEPI; Anti-Proepithelin
Storage: -20C
Application: Anti-GRN antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem Physiol Actions: GRN (granulin) is a growth and survival factor, which is involved in drug resistance and cancer. It is up-regulated in breast cancer, where it is responsible for tumorigenesis, drug resistance, invasion, metastasis and angiogenesis. It is up-regulated in non-small cell lung cancer (NSCLC), and it has potential as a prognostic marker and therapeutic target in the same. Serum levels of this protein correlate with visceral fat and increased level of liver enzymes. Thus, serum granulin level has potential as a marker for liver dysfunction.
