Red blood cell proteome has not been studied well until recently, as the large abundance of hemoglobin posed challenge to the detection of other cytosolic proteins in the linear dynamic range. However, in the last couple of years, due to emergence of various novel hemoglobin depletion strategies and more state-of-the-art detection techniques, a number of works on erythrocyte proteome have appeared in the literature. As a result, we now have much deeper information about both the membrane as well as the cytosolic proteins of erythrocytes. In this review, we have discussed the role of red cell proteome on the two most well-studied hemoglobin disorders, sickle cell disease and thalassemia, emphasizing on the differential expression of the redox regulator proteins and chaperones, in particular. We have also touched upon the importance of the association of the varying levels of hemoglobin variants, particularly HbE on the clinical manifestation of composite diseases like HbE beta thalassemia.
