XNBC2: Sodium bicarbonate cotransporter 2. SLC4A11. Expressed in changing segments of the pronephros.Around stage 30 - 32 expression is present in the early proximal and early distal tubules but excluded from the late proximal segment. By stage 35 expression in the early distal segment is lost, and the only site of expression is the early proximal segment.
