Medullary thick limb basolateral Cl- channels.
Chloride transport by the medullary thick ascending limb is a major determinant of urinary concentrating and diluting power and also of tubuloglomerular feedback. In this review, we discuss the electrophysiologic, regulatory, and molecular features of a Cl- channel present in basolateral membranes from the medullary thick ascending limb. Functional and immunohistochemical data support the view that rbCIC-Ka, a CIC Cl- channel cloned from rabbit kidney medulla, may be the Cl- channel which mediates basolateral Cl- efflux.
