The 2-oxoglutarate carrier protein (OGCP) catalyzes the transport of the 2-oxoglutarate into the mitochondrial matrix by an electroneutral exchange for malate or some other dicarboxylic acids. Using primers based on the bovine heart cDNA sequence, overlapping cDNA clones encoding the rat OGCP were isolated from total rat heart poly(A+) cDNA. The entire rat cDNA is 1149 bp in length with 5' and 3' untranslated regions of 41 and 163 bp, respectively. The open reading frame encodes a protein consisting of 314 amino acids. The amino acid sequence of the rat 2-oxoglutarate carrier is 97% identical to that of the 2-oxoglutarate from cow and human. By Northern blot analysis, hybridizing transcripts were found in rat heart, liver and brain.

Abstract
The 2-oxoglutarate carrier protein (OGCP) catalyzes the transport of the 2-oxoglutarate into the mitochondrial matrix by an electroneutral exchange for malate or some other dicarboxylic acids. Using primers based on the bovine heart cDNA sequence, overlapping cDNA clones encoding the rat OGCP were isolated from total rat heart poly(A+) cDNA. The entire rat cDNA is 1149 bp in length with 5' and 3' untranslated regions of 41 and 163 bp, respectively. The open reading frame encodes a protein consisting of 314 amino acids. The amino acid sequence of the rat 2-oxoglutarate carrier is 97% identical to that of the 2-oxoglutarate from cow and human. By Northern blot analysis, hybridizing transcripts were found in rat heart, liver and brain.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
