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
CABP3, also known as CABP5, belongs to a subfamily of calcium binding proteins, which share similarity to calmodulin. Calcium binding proteins are an important component of calcium mediated cellular signal transduction. Expression of CABP3 gene is retina-specific. The mouse homolog of CABP3 has been shown to express in the inner nuclear layer of the retina, suggested its role in neuronal functioning. The specific function of CABP3 gene is unknown. Study of the transcripts and genomic structure revealed that the 5 end of this gene is complementary and reverse to that of the CABP5 gene, and the sequence beyond the overlapping region is nearly identical to that of CABP5. Thus, these two genes encode the protein products with distinct N-terminal halves but identical C-terminal halves. CABP3 inhibits calcium-dependent inactivation of L-type calcium channel and shifts voltage dependence of activation to more depolarized membrane potentials. It is also involved in the transmission of light signals.
