Band 3 Protein (Anion Exchanger 1 / AE1)
Product Code: QA-BND01 CAS Number: 158475-15-1 (Band 3 824-829, human) Sequence: YVKRVK (824-829, human) Molecular Formula: C37H65N11O8 (824-829)
Overview
Band 3 protein, also known as anion exchanger 1 (AE1) or SLC4A1, is the most abundant integral membrane protein of the erythrocyte membrane, accounting for approximately 25% of the membrane surface. It mediates the electroneutral exchange of chloride for bicarbonate (the "chloride shift"), essential for CO2 transport from tissues to the lungs.
