Popis: A protein solubilisation buffer for 2D analysis must solubilise proteins effectively, without disturbing the native charge of the proteins. Urea based solubilisation buffers solubilise proteins effectively, however can modify the native charge of the proteins, due to carbamylation. Urea exists in equilibrium with ammonium cyanate that modifies α- and ε-amino groups, inducing changes in the isoelectric point of proteins leading to artifactual results.

Popis: GPRC6A (G protein-coupled receptor family C group 6 member A) is a 928 amino acid protein encoded by the mouse Gprc6a gene. GPRC6A is a member of the G protein-coupled receptor 3 family. This receptor is activated by both amino acids and extracellular concentration of calcium ions. The activity of GPRC6A is mediated by a G protein that activates a phosphatidylinositol-calcium second messenger system. GPRC6A senses changes in the extracellular concentration of calcium ions, suggesting that it may mediate extracellular calcium-sensing responses in osteoblasts. Osteocalin stimulates the activity of GPRC6A in the presence of calcium. GPRC6A also acts as a receptor for amino acids, with a preference for basic amino acids such as L-Lys, L-Arg and L-ornithine. Its affinity for amino acids suggests that it may act as a regulatory component of the urea cycle. GPRC6A is expressed at high levels in liver, lung, spleen and heart, and at lower levels in kidney, skeletal muscle and brain.

Popis: Kidney-Type Arginase (ARG2) is a member of the arginase family. Arginase is a manganese-containing enzyme which catalyses the hydrolysis of arginine to ornithine and urea. ARG2 is highly expressed in kidney and prostate, not founded in the liver, heart and pancreas. ARG2 has been implicated in the regulation of the arginine/ornithine concentrations in the cell. ARG2 may take part in the regulation of extra-urea cycle arginine metabolism and in down-regulation of nitric oxide synthesis. The extrahepatic arginase functions to regulate L-arginine bioavailability to NO synthase.

Popis: Argininosuccinate Synthase (ASS1) is an urea cycle enzyme with a tetrameric structure composed of identical subunits. ASS1 is involved in the synthesis of arginine and catalyses that condensation of citrulline and aspartate to argininosuccinate using ATP. ASS1 is important to the urea cycle as it catalyses the important second last step in the arginine biosynthetic pathway. ASS1 mainly expressed in periportal hepatocytes, but also in most other body tissues. A deficiency of ASS1 causes citrullinemia (CTLN1), an autosomal recessive disease which is characterised by severe vomiting spells and mental retardation.
