Control peptide for A0225-03A (affinity purified antibody) and A0225-03 (antiserum). Synthetic peptide 20aa sequence mapping near the N-terminus of rat ACC-2. No significant sequence homology is seen with ACC-1 or any other protein. Species Sequence Homology: Mouse: 75%, human: 60%. In cells, excess of metabolic fuel is converted into fatty acids in cytosol and oxidized later in mitochondria to generate ATP and acetyl-CoA. In fatty acid synthesis, catalytic formation of malonyl-CoA (precursor for long-chain fatty acyl-CoA, LCFA-CoA) from acetyl-CoA by Acetyl-CoA carboxylase (ACC-1) is the rate limiting step. The translocation of LCFA-CoA from cytosol to mitochondria is catalyzed by two carnitine palmitoyl transferases (CPT-1 & CPT-2) and regulated by ACC-2, the rate limiting step of mitochondrial fatty acid b-oxidation. Activities of ACC-1 and 2 are regulated by their phosphorylation by 5-AMP-activated protein kinase (AMPK). Diabetes deranges AMPK master-switch and represses the ACC-1 gene- expression and stimulates excessive fatty acid oxidation which in turn interferes with glucose metabolism. ACC-2 (rat 2456aa, human 2483aa, ~280kD, chromosome 12q24.1), also known as ACC-beta, is predominantly present in heart and skeletal muscle and to a lesser extent in liver. An additional ACC-2 isoform (270kD) is present in liver. In contrast to ACC-1, which is cytosolic and catalyzes only fatty acid synthesis, ACC-2 colocalizes with CPT-1 in the contact sites of the mitochondrial membranes and regulates mitochondrial fatty acid oxidation as well by inhibiting CPT-1 by its product malonyl-CoA. ACC-2 contains an unique 114aa long N-terminus peptide, accounting in part, for its regulatory role in fatty acid oxidation. ACC2 deficient mice accumulate 10-30 fold less malonyl-CoA in heart and muscle and show 50% less fat in the adipose tissue. Applications: Suitable for use in ELISA and Antibody Blocking. Not suitable for use in Western Blot due to low molecular weight. Other applications not tested. Recommended Dilution: ELISA: 50-100ng of control peptide/well. Antibody Blocking: 5-10ug per 1ug A0225-03A (affinity purified antibody) or per 1ul A0225-03 (antiserum). Optimal dilutions to be determined by the researcher. Species sequence homology: Mouse: 75% Human: 60% Storage and Stability: May be stored at 4C for short-term only. For long-term storage, store at -20C. Aliquots are stable for at least 6 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
Purity: Highly purified
