Rabbit Anti-Arginase II/FITC Conjugated antibody
background:
Arginase I (also designated liver-type arginase), which is expressed almost exclusively in the liver, catalyzes the conversion of arginine to ornithine and urea (1). The human arginase I gene, which maps to chromosome 6q23, encodes a 322 amino acid protein. Arginase I exists as a homotrimeric protein and contains a binuclear manganese cluster (2-4). Arginase II catalyzes the same reaction as arginase I, but differs in its tissue specificity and subcellular location (5,6). Specifically, arginase II localizes to the mitochondria (5,6). Arginase II is expressed in non-hepatic tissues, with the highest levels of expression in the kidneys, but, unlike arginase I, is not expressed in liver (5,6). The human arginase II gene, which maps to chromosome 14q24.1, encodes a 354 amino acid protein (3,5-7). In addition, arginase II contains a putative amino-terminal mitochondrial localization sequence (5,6).
Function:
May play a role in the regulation of extra-urea cycle arginine metabolism and also in down-regulation of nitric oxide synthesis. Extrahepatic arginase functions to regulate L-arginine bioavailability to NO synthase. Since NO synthase is found in the penile corpus cavernosum smooth muscle, the clitoral corpus cavernosum and the vagina, arginase II plays a role in both male and female sexual arousal. It is therefore a potential target for the treatment of male and female sexual arousal disorders.
Subunit:
Homotrimer.
Subcellular Location:
Cytoplasm.
Tissue Specificity:
Expressed most strongly in kidney and prostate, much less strongly in the brain, skeletal muscle, placenta, lung, mammary gland, macrophage, uterus, testis and gut, but apparently not in the liver, heart and pancreas.
Similarity:
Belongs to the arginase family.
