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 ...
MBL deficiency or mannose-binding lectin deficiency is an illness that has an impact on immunity. Low levels of mannose-binding lectin, an immune system protein, are present in the blood of those who have this illness. It's unclear if this deficiency increases the risk of recurrent infections in those who are affected.
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.

Parainfluenza hemagglutinin-neuraminidase: a type of hemagglutinin-neuraminidase produced by parainfluenza, which is closely associated with both human and veterinary disease. [17] Mumps hemagglutinin-neuraminidase: a kind of hemagglutinin that the mumps virus (MuV) produces. [18] Hemagglutinin: the PH-E form of phytohaemagglutinin.
Structure of mannose in its α-D mannopyranose form. Mannan is a polymer of mannose.. The lectin pathway or MBL pathway is a type of cascade reaction in the complement system, similar in structure to the classical complement pathway, [1] in that, after activation, it proceeds through the action of C4 and C2 to produce activated complement proteins further down the cascade.
The L-like lectin domain has an overall globular shape composed of a beta-sandwich of two major twisted antiparallel beta-sheets. The beta-sandwich comprises a major concave beta-sheet and a minor convex beta-sheet, in a variation of the jelly roll fold .
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 ...
In molecular biology, the galactose binding lectin domain is a protein domain. It is found in many proteins including the lectin purified from sea urchin ( Anthocidaris crassispina ) eggs, SUEL. This lectin exists as a disulfide -linked homodimer of two subunits; the dimeric form is essential for hemagglutination activity. [ 1 ]
