      Adipose tissue is an energy reserve in animals, and in nondomestic species it is strictly regulated. Adipose cells produce and secrete numerous physiologically important proteins that help regulate whole body metabolism, such as leptin and Acrp30. Fasting causes significant changes in nutrient metabolism and many of these changes are controlled by transcription factors that regulate rate-limiting enzymes. An important transcription factor that mediates metabolic processes induced by fasting is peroxisome proliferator-activated receptor alpha (PPAR alpha). PPAR alpha has recently been reported to target a novel gene encoding the secreted protein FIAF (fasting-induced adipose factor). FIAF is expressed predominantly in adipose tissue and is strongly upregulated in white adipose tissue and the liver under fasting conditions. Initial studies suggest that FIAF represents a novel endocrine signal helping to regulate metabolism, especially under fasting conditions.

    靶标

    • 功能

      Protein with hypoxia-induced expression in endothelial cells. May act as a regulator of angiogenesis and modulate tumorgenesis. Inhibits proliferation, migration, and tubule formation of endothelial cells and reduces vascular leakage. May exert a protective function on endothelial cells through an endocrine action. It is directly involved in regulating glucose homeostasis, lipid metabolism, and insulin sensitivity. In response to hypoxia, the unprocessed form of the protein accumulates in the subendothelial extracellular matrix (ECM). The matrix-associated and immobilized unprocessed form limits the formation of actin stress fibers and focal contacts in the adhering endothelial cells and inhibits their adhesion. It also decreases motility of endothelial cells and inhibits the sprouting and tube formation.
    • 组织特异性

      Expressed at high levels in the placenta, heart, liver, muscle, pancreas and lung but expressed poorly in the brain and kidney.
    • 序列相似性

      Contains 1 fibrinogen C-terminal domain.
    • 翻译后修饰

      N-glycosylated.
    • 细胞定位

      Secreted. Secreted > extracellular space > extracellular matrix. The unprocessed form interacts with the extracellular matrix. This may constitute a dynamic reservoir, a regulatory mechanism of the bioavailability of ANGPTL4.

      Question

      Hi, I ordered the antibody (anti-angiopoitin-like 4, ab2920) this week, today I checked the expression of angiopoitin-like 4 in the lysate of 3T3-L1 adipocytes, and found that Western result showed many specific bands, the concentration of the antibodyIused in the experiment is 2ug/ml, I think this antibody is not good. Can you refund? Thanks for you consideration.

      Asked on Sep 17 2012

      Answer

      Thank you fro bringing this to our attention. Are you seeing a band at 50 kDa, and if so, is it more intense than the other bands? Where do the other bands appear in the blot? If you can attach an image, the may help me understand what is going on.

      It is possible the antibody is defective but we ask our customer to provide a few details of their protocol, in the hope that we can suggest a modification that will improve the result. If not, I will send a refund.

      Can you please tell me how the samples are prepared, in particular, whether or not you are using protease inhibitors? Are the samples reduced and denatured?

      How is the membrane blocked before incubation with the antibody? And finally, are you confident that the secondary antibody is effective and not reacting with proteins in the sample?

      I look forward to your reply.

      Question

      BATCH NUMBER -- NOT SPECIFIED -- ORDER NUMBER -- NOT SPECIFIED -- DESCRIPTION OF THE PROBLEM Multiple bands I have problem to identify the right band . your antibody detects two possibly relevant bands - one week around 50 kDa and one quite strong around 30 kDa. In your datasheet 50 kDa is predicted as appearent protein size but in literature (i.e. Koster et al. Endocrinology 146: 4943 - 4950) Angptl-4 is reffered as 35 kDa protein. What band is the right band?

      Asked on Oct 15 2007

      Answer

      Thank you for your enquiry. The predicted KDa that this target should run at (Swiss Prot) is 46KDa, there is no indication of an alternate isoform of this target that I have been able to source. The paper cited below appears to indicate that the full length target observed usually as a single band at 45KDa is the unprocessed form; however proteolytic cleavage is also reported in this paper. Where this occurs the author suggests that a band of 25-30KDa may be observed. http://www.jbc.org/cgi/reprint/M403058200v1.pdf I am unsure as to the conditions that dictate the cleavage for this target; however it does sound like you may be detecting both forms. Since the rabbit is a pab (CQGPKGKDAPFKDSE) and will detect multiple epitopes it is possible that both forms may be detected. Should you have any further questions then please do not hesitate to get back in touch with me.

      Asked on Aug 21 2004

      Answer

      Thank you for your enquiry and patience. To our knowledge, this antibody has only been tested for application in Western blotting, and so we don't have any information about how ab2920 works in IP. Have you done a positive control? I would suggest running a Western with rat adipose tissue extract to ensure that the antibody is functioning properly. Also, when did you purchase this antibody? What is the lot number (located on the vial)? On the datasheet it is recommended to store this antibody at +4°C short term and aliquot and store at -20°C or -80° for longer term storage.
