Protein

Kininogen-1a

Gene
N/A
Organism
Bombina maxima (Giant fire-bellied toad) (Chinese red belly toad)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Bombinakinin-GAP: plays a role in the control of feeding by the brain; intracerebroventricular administration of the peptide induced significant decrease in food intake in rats. Inhibits the bradykinin-induced in vitro relaxation of rat arterial smooth muscle. May target bradykinin receptors (BDKRB).2 Publications
