Cse1l is a negative regulator of CFTR-dependent fluid secretion.

ABSTRACT: Transport of chloride through the cystic fibrosis transmembrane conductance regulator (CFTR) channel is a key step in regulating fluid secretion in vertebrates [1, 2]. Loss of CFTR function leads to cystic fibrosis [1, 3, 4], a disease that affects the lungs, pancreas, liver, intestine, and vas deferens. Conversely, uncontrolled activation of the channel leads to increased fluid secretion and plays a major role in several diseases and conditions including cholera [5, 6] and other secretory diarrheas [7] as well as polycystic kidney disease [8-10]. Understanding how CFTR activity is regulated in vivo has been limited by the lack of a genetic model. Here, we used a forward genetic approach in zebrafish to uncover CFTR regulators. We report the identification, isolation, and characterization
