GO Classification

Functions

bicarbonate transmembrane transporter activity / chloride transmembrane transporter activity / oxalate transmembrane transporter activity / secondary active sulfate transmembrane transporter activity / solute / sulfate transmembrane transporter activity

Processes

anion transport / cellular response to cAMP / intracellular pH elevation / ion transport / membrane hyperpolarization / sperm capacitation

Components

apical plasma membrane / brush border membrane / membrane / plasma membrane / sperm midpiece

General Function

Chloride/bicarbonate exchanger. Mediates the efficient absorption of chloride ions in the colon, participating in fluid homeostasis. Plays a role in the chloride and bicarbonate homeostasis during sperm epididymal maturation and capacitation.

Specific Function

Bicarbonate transmembrane transporter activity
