Calcium dependent polymerization of lactoferrin



Calcium dependent polymerization of lactoferrin



Biochemical & Biophysical Research Communications 101(1): 88-95



Lactoferrin, which has a MW of .apprx. 77,000, undergoes polymerization in Ca-containing fluids. The predominant species is a tetramer. Preliminary evidence indicates that the tetramer is also found in human serum, tears and breast milk. When the lactoferrin monomer and the tetramer were tested for biological activity in a system that is known to be highly sensitive to an inhibitory effect of lactoferrin (the production of granulocyte monocyte colony-stimulating activity) only the monomeric form of lactoferrin was inhibitory.
