Which of these is an iron binding salivary protein giving support to our immune system?

Lactoferrin (LF) also known as lactotransferrin (LTF) is a multifunctional protein of the transferrin family. It is a globular glycoprotein widely represented in various secretory fluids such as milk, saliva, tears and nasal secretions. It is folded into two globular units, each capable of binding up to 1.4 mg iron/g of protein. Lactoferrin is one of the components of the immune system of the body. It has antimicrobial activity (bacteriocide, fungicide) and is part of the innate defense mainly at mucoses.
