Corticotropin & CRF Peptides — frequently asked
What does this family include?
It includes corticotropin-releasing factor and its receptor-derived peptides together with numbered fragments of the prepro-corticotropin-lipotropin (POMC) precursor. The grouping reflects the shared corticotropin axis rather than a single peptide sequence or receptor.
Why is CRF widely studied?
CRF sits at the top of the stress axis, driving pituitary ACTH release through CRF receptor 1. Researchers use it in neuroendocrine, behavioural and receptor pharmacology studies, often alongside urocortins and CRF receptor 2 reagents for comparison.
What are the numbered precursor fragments for?
Fragments such as prepro-corticotropin-lipotropin (107-120) correspond to defined regions of the POMC sequence. They are typically used as immunogens, assay standards or markers of precursor processing rather than as peptides with independently established receptor activity.
