The citrate (tricarboxylate) carrier transports citrate (or other tricarboxylates) across the inner membranes of mitochondria in an electroneutral exchange for inalate (or other dicarboxylic acids). We have determined the sequence of the human citrate transporter gene from overlapping genomic clones generated by polymerase chain reactions by use of primers and probes based on the rat cDNA sequence and on emerging sequences. The gene is spread over 2.8 kb of human DNA and is divided into eight exons. All the introns are located at the level of the sequences coding for the extramembranous loops (and not for the transmembrane segments) of the mature protein. The open reading frame of the human gene encodes the mature protein consisting of 298 amino acids, preceded by a presequence of 13 amino acids to help to target it into mitochondria. 84 identities and 106 highly conservative substitutions are present in CTPs from man to yeast. In addition, we have determined the sequences of two human pseudogenes related to the citrate carrier gene encompassing the coding sequence of the gene between nucleotides 260 and 720.
