Description
Plays a major role in tight junction-specific obliteration of the intercellular space, through calcium-independent cell-adhesion activity. Tryptophan hydroxylase (TPH; EC 1.14.16.4) is the rate-limiting enzyme in the synthesis of serotonin (5-hydroxytryptamine, or 5HT). 5HT is causally involved in numerous central nervous activities, and it has several functions in peripheral tissues, including the maintenance of vascular tone and gut motility. (Microbial infection) Acts as a receptor for hepatitis C virus (HCV) entry into hepatic cells
