The steroidogenic acute regulatory (StAR) protein performs the delivery of cholesterol from
the outer to inner mitochondrial membrane. This is considered the rate-limiting step of acute
steroid production, widely studied in mammals. However, there are only few reports
regarding the characterization and expression of StAR protein in non-mammalian
vertebrates. In this study, StAR protein sequence of Rhinella arenarum has been
characterized and deduced from interrenal and testis cDNA sequences. StAR encodes a …
