This salusin-b peptide belongs to the salusin family, newly discovered TOR-related peptides. TOR is a gene encoding a protein of the torsion dystonia family. Salusins are detected in many human tissues, plasma and urine, they are endocrine and/or paracrine factors. Hypotensive activity of salusin-beta is caused by depressing cardiac contractility. Administration of salusins to animals is associated with hypotension and bradycardia, salusins increase intracellular Ca2+ and induce cell mitogenesis.
