Material Safety Data Sheet (MSDS)

Spexin is a neuropeptide encoded by SPX genes, and homologs have been found amongst many vertebrates. The SPX genes encode a preprohormone that leads to the mature hormone spexin, which is highly conserved amongst higher vertebrates. Another form, SPX2, has been identified and named spexin 2. Both sequences of spexin and spexin 2 are highly conserved, suggesting they each play vital roles.

Like spexin, spexin 2 is widely expressed in various tissues. This is an amidated spexin-2 (53-70) peptide showing similar biological function to its non- amidated version. Spexin-2, when administered to rats, decreases heart rate and increases urine flow rate. Intraventricular NPQ(53-70) delivery also causes antinociceptive activity in mice’s warm water tail withdrawal assay.
