HA Tag Information

Human influenza hemagglutinin (HA) is a surface glycoprotein required for the infectivity of the human virus. The HA tag is derived from the HA-molecule corresponding to amino acids 98-106 has been extensively used as a general epitope tag in expression vectors. Many recombinant proteins have been engineered to express the HA tag, which does not appear to interfere with the bioactivity or the biodistribution of the recombinant protein. This tag facilitates the detection, isolation, and purification of the proteins.

The actual HA tag is as follows: 5' TAC CCA TAC GAT GTT CCA GAT TAC GCT 3' or 5' TAT CCA TAT GAT GTT CCA GAT TAT GCT 3' The amino acid sequence is: YPYDVPDYA.

Background Information
ICAM4, also known as CD242, is a member of the?immunoglobulin superfamily, ICAM family. ICAM4 contains 2?Ig-like C2-type (immunoglobulin-like) domains. It is similar to the intercellular adhesion molecule (ICAM) protein family. ICAM4 binds to the leukocyte adhesion LFA-1 protein. ICAM4's first reported receptors were CD11a/CD18 and CD11b/CD18. ICAM4 functions as a ligand for the monocyte/macrophage-specific CD11c/CD18. Deletion of the individual immunoglobulin domains of ICAM4 demonstrated that both its domains contain binding sites for CD11c/CD18. CD11c/CD18 is expressed on macrophages in spleen and bone marrow. Inhibition of erythrophagocytosis by anti-ICAM4 and anti-integrin antibodies suggests a role for these interactions in removal of senescent red cells.
