HA Tag Info

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

SCN2B plays a key role in the assembly, expression, and functional modulation of the heterotrimeric complex of the sodium channel. Voltage-gated sodium channels (NaV) are composed of one pore-forming alpha-subunit, which may be associated with either one or more beta-subunits. Alpha-subunits are composed for four homologous domains, each of which contains six transmembrane segments.They are responsible for action potential initiation and propagation in excitable cells, including nerve, muscle, and neuroendocrine cell types. SCN2B causes an increase in the plasma membrane surface area and in its folding into microvilli. SCN2B also interacts with TNR and may play a crucial role in clustering and regulation of activity of sodium channels at nodes of ranvier.
