Peptide PHI
Peptide PHI is a peptide which functions as a hormone.
Peptide histidine isoleucine is part of family that plays a vital role in the cell growth rate such as in the intestine as well as in brain. While PHI and other peptides belonging to the same family have somewhat similar chemical and biological function, however PHI has different structure from them. It contains composition contains 27 amino acid intestinal peptide. PHI functions specifically function in the G protein signaling pathway.
It also plays a role in the regulation of prolactin in humans. PHI functions through G protein, which is a transmembrane protein that causes the cascade phosphorylation. It located throughout the entire length of intestine while PHI is mostly concentrated in the colon region.
