Abstract
Phosphate transport protein (PTP) is a mitochondrial inner membrane protein responsible for the translocation of inorganic phosphate into the mitochondrial matrix. A full length cDNA clone encoding the PTP was isolated from the spruce budworm, Choristoneura fumiferana. The deduced amino acid sequence of the longest ORF of CfPTP cDNA showed high similarity with the amino acid sequences of PTPs cloned from several species. Phylogenetic tree analysis indicated that CfPTP occupied an intermediate position between vertebrates on the one side and yeast and nematodes on the other side. Studies on the developmental expression of CfPTP mRNA showed that higher levels of mRNA were present during the feeding and growing stages than during molting periods.
