Avian Sequence Context
Chicken gastrin provides a useful comparative model because its upstream sequence differs markedly from mammalian gastrin while retaining a related C-terminal receptor-active motif.
Avian gastrin biology also includes sulfated molecular forms. Sulfation is a defined chemical modification and should only be assumed when explicitly included in the product specification.
We recommend confirming modification state when published avian gastrin data are compared with synthetic material.
Research Applications
Applications include comparative endocrine biology, gastrointestinal physiology, peptide evolution and cross-species receptor studies.
Defined sulfation or other sequence modifications can be evaluated through Chemical Peptide Synthesis.
Frequently Asked Questions
Is chicken gastrin identical to human Gastrin-17?
No. The avian peptide differs substantially in sequence length and composition.
Is tyrosine sulfation automatically present?
No. Sulfation should only be assigned when it is explicitly included in the molecular specification.
