General annotation (Comments)

Function	Transferrins are iron binding transport proteins which can bind two Fe3+ ions in association with the binding of an anion, usually bicarbonate. Ref.21 Lactotransferrin has antimicrobial activity which depends on the extracellular cation concentration. Ref.21 Lactoferroxins A, B and C have opioid antagonist activity. Lactoferroxin A shows preference for mu-receptors, while lactoferroxin B and C have somewhat higher degrees of preference for kappa-receptors than for mu-receptors. Ref.21 The lactotransferrin transferrin-like domain 1 functions as a serine protease of the peptidase S60 family that cuts arginine rich regions. This function contributes to the antimicrobial activity. Ref.21
Catalytic activity	Preferential at -Arg-Ser-Arg-Arg-|- and -Arg-Arg-Ser-Arg-|-, and of Z-Phe-Arg-|-aminomethylcoumarin.
Subunit structure	Monomer.
Subcellular location	Secreted.
Sequence similarities	Belongs to the transferrin family. Contains 2 transferrin-like domains.
