To elucidate the genetic basis of salt-sensitivity in mammalian hypertension, we isolated six rat complementary DNAs by functional complementation in yeast. These genes were able to substitute for the salt-tolerant activity of HALI which confers salt tolerance by modulating the cation transport system in yeast. We identified these genes as beta-globin, lambda-crystallin, androgen-regulated protein, mitochondrial cytochrome b, a homologue of infant brain cDNA, and a novel gene, called salt-tolerant protein (STP). STP contains 1964 bp nucleotides and an open reading frame which encodes 496 amino acid residues. Northern blot analysis showed that STP mRNA is expressed in various rat tissues.

Higher dietary salt intake in humans is associated with higher BP, but the BP response to NaCl, so-called salt sensitivity, is heterogeneous among individuals. It has been postulated that modifications in cellular cation metabolism may be related to salt sensitivity in mammalian hypertension. The authors have isolated a novel rat complementary DNA, called salt-tolerant protein (STP), that can functionally complement Saccharomyces cervisiae HAL1, which improves salt tolerance by modulating the cation transport system. On high-salt (8% NaCl) diets, both Dahl salt-sensitive and salt-resistant rats displayed an elevated BP and increased STP mRNA expression. Immunohistochemistry using an anti-rat STP antibody demonstrated the presence of STP immunoreactivity in the proximal tubules. In cells that transiently expressed STP, the intracellular [Na+]/[K+] ratio was higher than that in control cells. STP contains predicted coiled-coil and Src homology 3 domains, and shows a partially high degree of nucleotide identity to human thyroid-hormone receptor interacting protein. These results suggest that STP may play an important role in salt sensitivity through cellular sodium metabolism by mediating signal transduction and a hormone-dependent transcription mechanism.

We have isolated a novel human cDNA coding for human salt-tolerant protein (HSTP), that is a homologue of the rat salt-tolerant protein (STP) and may contribute to salt-induced hypertension by modulating renal cation transport. The nucleotide sequence (1988bp) of the HSTP cDNA contains an open reading frame encoding a polypeptide comprising 545 amino acids, two residues fewer than the rat STP cDNA. The predicted amino acid sequence exhibits 92% identity to that of the rat protein. HSTP contains predicted coiled-coil domains and Src Homology 3 domain, and shows a high degree of identity to CIP4 (Cdc42 target protein) and human Trip 10 (thyroid-hormone receptor interacting protein). We have mapped the HSTP gene to human chromosome 19 by fluorescence in situ hybridization.
