UniProtKB - P04919 (B3AT_MOUSE)

Protein

Band 3 anion transport protein

Gene

Slc4a1

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Functions both as a transporter that mediates electroneutral anion exchange across the cell membrane and as a structural protein. Major integral membrane glycoprotein of the erythrocyte membrane; required for normal flexibility and stability of the erythrocyte membrane and for normal erythrocyte shape via the interactions of its cytoplasmic domain with cytoskeletal proteins, glycolytic enzymes, and hemoglobin. Functions as a transporter that mediates the 1:1 exchange of inorganic anions across the erythrocyte membrane. Mediates chloride-bicarbonate exchange in the kidney, and is required for normal acidification of the urine.By similarity

Interactioni

Subunit structurei

A dimer in solution, but in its membrane environment, it exists primarily as a mixture of dimers and tetramers and spans the membrane asymmetrically. Interacts (via cytoplasmic N-terminal domain) with ANK1 (via N-terminal ANK repeats); tetramer formation is critical for ankyrin association. Interacts with STOM. Isoform 2 interacts with TMEM139.By similarity
