Salusin may be a endocrine and/or paracrine factor able to increase intracellular calcium concentrations and induce cell mitogenesis. Salusin may also be a potent hypotensive peptide (By similarity). Isoform 2 is ubiquitously expressed. Salusin-beta peptide is derived from isoform 2. Belongs to the ClpA/ClpB family. Torsin subfamily. Salusin-beta detected systemically according to PubMed:18344632 represents the putative rat salusin consisting of 40 amino acid residues or a shorter fragment produced by an unknown processing mechanism. No salusin-alpha homolog is detected in rat tissues.
