  • In the last decade, the number of overweight children and adults has increased all over the world. In Indonesia,  obesity  needs  serious  management  because  it  is  multi-factorial  etiology.  One  of  the predominant  factors  of  obesity  is  excessive-appetite.  This  paper  aims  to  discuss  a  gut  hormone  called cholecystokinin  (CCK),  which  has  been  proven  to  be  able  to  decrease  appetite.  CCK  has  a  short  term anorectic effect, which becomes the reason for the hormone to be one of therapeutic targets of obesity in the future.  CCK  is  produced  in  the  enteroendocrine  cell  along  the  small  gut  mucous  and  the  secretion  is stimulated  by  protein  and  fat  through  signal  transduction  mechanisms  called  G  Protein  Coupling Receptor  (GPCR),  GPR  93.  Then  they  activate  Extracellular  Signal-Related  Kinase  (ERK)  1/2  through Gαq and Gαi signal transduction. Soybean contains a bioactive protein, β-conglycinin (BconP) subunit–β, which  has  been  proven  to  be  the  best  inducer  for  CCK  secretion.  The  well-known  signal  transduction pathway is Gαq-coupled  GPCR,  which  influences  the  calcium  signal  and  activates  Protein  Kinase  C (PKC). However, the downstream signaling to complete the pathway remains unclear and further study will be needed to explore the whole process.   Keywords: signal transduction, cholecystokinin, fat, protein, β-conglycinin
