We research on carbohydrate-binding proteins (Lectin) in marine invertebrates
as polifera, echiura, echinoderm, and mollusuk. Marine invertebrates adapt in aquatic environmets against enemys, hosts,
chemicals, and physics conditions. These proteins control themselves and
act for important biological functions.
Some marine organisms are expected as useful biochemical resources whch develop our health. Thiese proteins is also seemed to be industrial targets after genome project. Students
obtain here biochemical skills for proteins of marine animals through the
researchs as protein purification, primary structure analysis, and functional study
with advanced instruments.
Glycoconjugates, as glycoprotein, glycolipids, and proteoglycans are important molecules
for living system. As ABO-blood type, some of oligosaccharides are essential
for biological recognition systems. Oligosaccharides structures also change
sometimes through the development and disease of animals. Specific receptor
may interact with glycans on cell membrane and body fluids through protein-glycan
interaction.
Lectin is a excellent protein, which can read the structure of oligosaccharide
of glycoconjugates and chatch specifically and non-covalently. They function
to cell-cell interactions, body defences, and cellar proliferations. We purify and identify newly lectins from lower animals and try to appare
their physiological role and apply it for our life.
