Arginase 2 Antibody Human, Mouse and Rat WB. Western blot analysis of ARG2 in human HepG2, K562, 293T and Caco-2 cells, rat kidney and colon tissues, and mouse kidney and colon tissues using Arginase 2 Antibody. Samples (30 ug/lane) were separated by 10% SDS-PAGE under reducing conditions and transferred to nitrocellulose. Lanes 1-8: HepG2, K562, 293T, Caco-2, rat kidney, rat colon, mouse kidney and mouse colon, respectively. The membrane was incubated with the antibody at 0.5 ug/ml overnight at 4°C, followed by HRP-conjugated secondary antibody and ECL detection. A specific band was detected at approximately 39 kDa, consistent with the expected molecular weight of ARG2.

Description

Arginase 2 Antibody / Mitochondrial Arginase Antibody recognizes ARG2, one of two mammalian arginase enzymes responsible for hydrolyzing L-arginine to ornithine and urea. Unlike the predominantly cytosolic and liver-associated ARG1 isoform, ARG2 contains an N-terminal mitochondrial targeting sequence and is localized primarily to mitochondria. ARG2 is expressed in numerous extrahepatic tissues, including kidney and several cell populations of the cardiovascular and immune systems. Its distinct subcellular localization and tissue distribution make Arginase 2 an important target for studies of arginine metabolism, mitochondrial biology and metabolic regulation.

ARG2 contributes to cellular L-arginine metabolism by competing for substrate that can also be utilized by nitric oxide synthases. Changes in arginase activity can therefore influence the availability of L-arginine for nitric oxide production. This relationship is particularly relevant in vascular biology, where increased ARG2 activity has been investigated in connection with reduced nitric oxide bioavailability, endothelial dysfunction and altered vascular homeostasis. An Arginase 2 Antibody can support research examining the relationship between mitochondrial arginine metabolism, nitric oxide signaling and cardiovascular cell function.

The ornithine generated through ARG2-mediated arginine hydrolysis can enter metabolic pathways involved in the production of polyamines and proline. These metabolites contribute to processes including cell proliferation, tissue remodeling and extracellular matrix biology. Through its effects on arginine availability and downstream metabolites, Mitochondrial Arginase can therefore influence cellular metabolism beyond urea production. ARG2 expression and activity have been investigated in metabolic disease, vascular dysfunction, kidney biology and other conditions in which altered amino acid metabolism contributes to changes in cellular physiology.

ARG2 is also relevant to immunology and cancer research. Arginine availability can influence the activity and metabolic state of immune cells, and arginase-dependent pathways participate in the regulation of inflammatory and immune responses. ARG2 expression has been studied in macrophages and other immune cell populations as well as within tumor-associated metabolic environments. Altered arginine metabolism can affect interactions between immune and tumor cells, making ARG2 relevant to studies of immunometabolism, inflammation and mechanisms that regulate antitumor immune responses.

As the mitochondrial member of the mammalian arginase family, ARG2 provides a useful target for distinguishing extrahepatic and mitochondrial arginine metabolism from the predominantly hepatic functions associated with ARG1. Its connections to nitric oxide production, ornithine metabolism, vascular function and immune regulation make it relevant across metabolic, cardiovascular, immunological and cancer research. NSJ Bioreagents supplies antibodies to ARG2 and other proteins involved in amino acid metabolism and cellular signaling. An Arginase 2 Antibody can support studies of mitochondrial arginase expression, arginine metabolism, nitric oxide signaling, vascular biology, immunometabolism and metabolic regulation.
