Abstract

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 (1988 bp) 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 HSTPgene to human chromosome 19 by fluorescence in situhybridization.
