Aquaporin Channel (Colon) (AQP (Colon))

Target
AQP (Colon)
Molecular classification
Integral membrane protein, Water channel, Aquaporin
01

Overview

Aquaporin channels (AQPs) are integral membrane proteins that facilitate water transport across cell membranes. In the colon, AQP3 is the predominant subtype, but AQP4 and AQP8 also contribute. These channels regulate water absorption and secretion, crucial for intestinal fluid homeostasis and fecal consistency. Altered AQP expression or function is implicated in constipation and diarrhea, making them potential therapeutic targets. Regulation occurs via hormones, intestinal contents, and inflammatory mediators.
