GYPA/CD235a Protein, Cynomolgus (HEK293, His)

The GYPA/CD235a protein is an important component of the ankyrin-1 complex, which is critical for the stability and shape of the red blood cell membrane. GYPA/CD235a Protein, Cynomolgus (HEK293, His) is the recombinant cynomolgus-derived GYPA/CD235a protein, expressed by HEK293 , with C-His labeled tag. The total length of GYPA/CD235a Protein, Cynomolgus (HEK293, His) is 72 a.a., with molecular weight of 30-45 kDa.

GYPA, also known as Glycophorin A, serves as a pivotal component within the ankyrin-1 complex, a multiprotein assembly crucial for maintaining the stability and shape of the erythrocyte membrane. As the major intrinsic membrane protein of erythrocytes, GYPA contributes significantly to membrane integrity. Its N-terminal glycosylated segment, projecting beyond the erythrocyte membrane, bears MN blood group receptors and plays a vital role in erythrocyte function. GYPA is particularly essential for the optimal activity of SLC4A1, and its presence is required for the high activity of this membrane transporter. Moreover, GYPA is implicated in the translocation of SLC4A1 to the plasma membrane. Beyond its structural role, GYPA acts as a receptor for influenza virus, Plasmodium falciparum erythrocyte-binding antigen 175 (EBA-175), and Hepatitis A virus (HAV), highlighting its diverse functional repertoire. Existing as a homodimer, GYPA is an integral part of the ankyrin-1 complex, collaborating with other proteins such as ANK1, RHCE, RHAG, SLC4A1, EPB42, GYPB, and AQP1 in the erythrocyte membrane, thereby contributing to the overall structural integrity and functionality of these blood cells. The interaction with SLC4A1 results in the formation of a heterotetramer, emphasizing the cooperative nature of the erythrocyte membrane complex.
