Expressioni

Tissue specificityi

Red blood cells.

Developmental stagei

In birds, the alpha-D chain occurs in a minor hemoglobin component, called hemoglobin d, which is expressed in late embryonic and adult life.

Interactioni

Subunit structurei

Heterotetramer of two alpha-D chains and two beta chains. The component D forms dimers of tetramers upon deoxygenation.
