Neuropeptide EI (NEI) — frequently asked
What is neuropeptide EI?
Neuropeptide EI is an amidated peptide generated from the prepro-melanin-concentrating hormone precursor. It is named after the glutamic acid and isoleucine residues at its ends and is expressed in the same hypothalamic neurons as melanin-concentrating hormone.
Does neuropeptide EI have a known receptor?
No specific receptor has been firmly identified. Reported behavioural and endocrine effects come mainly from central administration studies, so mechanistic conclusions remain provisional and are usually discussed alongside data on the co-produced melanin-concentrating hormone.
Which species sequences are needed?
The mature peptide is identical in human, rat and mouse, so one synthetic sequence serves all three models. A tyrosine-extended variant is supplied separately because the native peptide lacks a convenient site for radioiodination in tracer applications.
