Why receptor families matter

Most peptide signalling runs through G protein-coupled receptors (GPCRs), whose shared structure explains why analogues in one family are studied with similar assays (Rosenbaum et al., 2009). The wider field is reviewed by Muttenthaler et al. (2021).

How to use this index

Open a family's topic page, then each compound's /ref page for identity data and its /learn brief for handling, QC and literature.

How much does Research Peptide Families: A Topic Index cost in the UK?

Frequently asked questions

Why group peptides into families?

Peptides in one family usually share a receptor target or a structural origin, so their literature, analytical methods and handling notes overlap.

How are the families defined here?

By the receptor system or structural origin described in the literature, for example ghrelin-receptor agonists, GLP-1/GIP receptor analogues or melanocortin receptor ligands.

Is a family a recommendation?

No. It is a reading aid for literature and catalogue navigation only.

Where are the per-compound facts?

On each /ref page (identity data with sources) and each /learn research brief.

Are blends listed?

Yes, under 'blends and stacks', with each component documented separately.
