What is the function of hemagglutinin?

Hemagglutinin (HA) or haemagglutinin (BE) is an antigenic glycoprotein found on the surface of the influenza viruses (as well as many other bacteria and viruses). It is responsible for binding the virus to the cell that is being infected. The name "hemagglutinin" comes from the protein's ability to cause red blood cells (erythrocytes) to clump together ("agglutinate") in vitro [1]. http://www.wikidoc.org/index.php/Hemagglutinin

What is hemagglutinin inhibitor titer?

Haemagglutination inhibition test Influenza virus has two important surface glycoproteins-the haemagglutinin (HA) and the neuraminidase (NA). Antigenic classification and subtyping of influenza viruses is based on these two glycoproteins. HA plays a key role in virus cell entry by binding to cell surface receptors, which are found also on red blood cells of certain species. Binding to red cells results in haemagglutination, which can be observed as a carpet of agglutinated red cells at the bottom of a tube or microtitre well. In the haemagglutination inhibition test (HIT), antibody directed against the viral haemagglutinins block the virus from binding to the blood cells and thus inhibits the haemagglutination reaction

What Influenza A subtypes can infect humans?

There have been several over the decades. The first one found was the one that pigs get (hence the name), H1N1, in the1930's. Then when people started being able to catch that one or mutations of that one, there is speculation that there could have been several others in retrospect, including the "Spanish Flu" that started the influenza pandemic in 1918, but there are no longer samples to test that hypothesis. Then there was the 1976 swine flu (see more in related questions), and now most recently, the H1N1/09 swine flu, the one that caused the 2009 pandemic and still circulating and making people ill today. See the related questions below, about when swine flu started and what caused the 2009 swine flu to develop, for more details.

How can the amino acid sequence determine protein shape and function?

Amino acids have different properties according to their R group. They can be negative, positive, aromatic, etc. - which will affect where that amino acid will be found, and what functions it will perform. For example, Glutamate and Aspartate are negative amino acids, and so are most likely to be found on the surface of proteins. Whereas Leucine and Methionine are hydrophobic, so they will be found in the interior of the protein. The sequence of amino acids causes the protein to fold in a certain way to find the most energetically and functionally favourable shape.


Who discovered the computer virus at first?

The first virus was made in Chauburji, Lahore, Pakistan, 1986Two programmers named Basit and Amjad Farooq Alvi, .replace the executable code in the boot sector of a floppy disk with their own code designed to infect each 360kb floppy accessed on any drive. Infected floppies had " Brain" for a volume label.
