In medicine these proteins are useful and are used as a mitogen to trigger T-lymphocyte cell division and to activate latent HIV-1 from human peripheral lymphocytes.In neuroscience, anterograde tracing is a research method that uses the protein product phytohaemagglutinin PHA-L as a molecular tracer that can be taken up by the cell and transported across the synapse into the next cell thereby ...
Illustration showing influenza virus attaching to cell membrane via the surface protein hemagglutinin. Hemagglutinins (alternatively spelt haemagglutinin, from the Greek haima, 'blood' + Latin gluten, 'glue') are homotrimeric glycoproteins present on the protein capsids of viruses in the Paramyxoviridae and Orthomyxoviridae families.
Stillmark isolated ricin, an extremely toxic hemagglutinin, from seeds of the castor plant (Ricinus communis). The first lectin to be purified on a large scale and available on a commercial basis was concanavalin A, which is now the most-used lectin for characterization and purification of sugar-containing molecules and cellular structures. [36]
BanLec (also BanLec-I or Banana lectin) is a lectin from the jacalin-related lectin family isolated from the fruit of the bananas Musa acuminata [1] and Musa balbisiana. [2] BanLec is one of the predominant proteins in the pulp of ripe bananas [ 3 ] and has binding specificity for mannose and mannose-containing oligosaccharides . [ 2 ]
Soybean agglutinins (SBA) also known as soy bean lectins (SBL) are lectins found in soybeans. It is a family of similar legume lectins. As a lectin, it is an antinutrient that chelates minerals. In human foodstuffs, less than half of this lectin is deactivated even with extensive cooking (boiling for 20 minutes). [1]

C-type lectin domain family 4 member M is a protein that in humans is encoded by the CLEC4M gene. [5] CLEC4M has also been designated as CD299 ( cluster of differentiation 299). This gene encodes L-SIGN (liver/lymph node-specific intracellular adhesion molecules-3 grabbing non-integrin), a type II integral membrane protein that is 77% identical ...
Collectin MBL is involved in activation of the lectin complement pathway. [32] [33] There are three serine proteases, MASP-1, 2 and 3 (MBL-associated serine proteases), which participate in activation of the lectin pathway. MASP-2 has a cleavage activity and it is essential for forming lectin C3 and C5 convertases and for activation of the ...
