Neuropeptide Q (NPQ) — frequently asked
What is neuropeptide Q?
Neuropeptide Q, usually abbreviated NPQ, is an alternative name for spexin. It is a short amidated peptide processed from a small precursor and was identified through comparative genomic analysis rather than conventional biochemical purification.
How does NPQ relate to galanin?
Published work reports that the peptide binds the galanin receptors GALR2 and GALR3 with little activity at GALR1. This places it within the galanin receptor system despite limited sequence similarity to galanin itself.
Why are glycine-extended forms supplied?
Peptides such as NPQ-Gly represent processing intermediates that precede the amidated mature form. They are useful for studying precursor processing and for validating antibodies or assays that must distinguish intermediates from the final peptide.
