Recombinant protein corresponding to Pro1185-Phe1352 from human ACACA, expressed in E. coli.
ACACA (Acetyl-CoA carboxylase alpha/1; also ACC1and biotin carboxylase) is a 260-265kD cytoplasmic, phosphorylated biotinylenzyme.It is widely expressed, and found to be concentrated in hepatocytes, adipocytes and lactating mammary epithelium. It is one of two gene products (ACACB/beta being the other) that catalyze the formation of malonylCoA from acetylCoA. The formation of malonylCoA by ACACA is a rate limiting step in fatty acid synthesis; malonylCoA formed by ACACB acts as a regulator of CPT1 during fatty aciid oxidation. Human ACACA is 2346aa in length. It contains an N-terminal acetylated Met, one ATPGrasp-domain (aa275-466) with an embedded biotin carboxylation domain (aa117-618), a biotinyl binding region (aa752-818), and a carboxyl transferase domain (aa1698-2194). There are at least 17 utilized phosphorylation sites, and two acetylated Lys. ACACA exists as either a dimer or higher order oligomer. Multiple splice variants exist. One possesses an alternative start site at Met79, a second utilizes an alternative start site 37aa upstream of the standard site, and a third(called PIII) shows a 17aa substitution for aa1-75. Over aa1185-1352, human ACACA shares 95% aa identity with mouse ACACA, and 97% aa identity with both ovine and bovine ACAC-A. Applications: Suitable for use in Western Blot and ELISA. Other applications not tested. Recommended Dilutions: Western Blot: 1ug/ml Optimal dilutions to be determined by the researcher. Positive Control: Lysates of A431 human epithelial carcinoma cell line, HCT116 human colorectal carcinoma cell line, HepG2 human hepatocellular carcinoma cell line and C2C12 mouse myoblast cell line Storage and Stability: Lyophilized and reconstituted products are stable for 12 months after receipt at -20C.
