• Marke: Biosynth
• Beschreibung: Perisulfakinin (PSK) is a cyclic peptide that has been isolated from the venom of the fly Phera insolita. PSK has a high affinity for protease activity and can be used as an inhibitor of proteases in control experiments. PSK is also an activator of cation channels and may be used as a neurotransmitter or neuromodulator in insects. The PSK peptide is present in dipteran species and can be seen by electron microscopy in their abdominal ganglia. PSK also activates Ca2+ influx into cells, which can lead to cell death. The PSK peptide is converted to cleavage products by enzymes, with bioassays being one way to measure these products.
