Chloride channel accessory 4, also known as CLCA4, is a protein which in humans CLCA4gene. The protein encoded by this gene is a chloride channel.[5] Protein structure prediction methods suggest the N-terminal region of CLCA4 protein is a zinc metalloprotease, and the protein is not an ion channel per se.[6]
