== Function ==
 +
[https://www.uniprot.org/uniprot/TRFL_HUMAN TRFL_HUMAN] Transferrins are iron binding transport proteins which can bind two Fe(3+) ions in association with the binding of an anion, usually bicarbonate.<ref>PMID:12535064</ref> <ref>PMID:22320386</ref> Lactotransferrin has antimicrobial activity which depends on the extracellular cation concentration.<ref>PMID:12535064</ref> <ref>PMID:22320386</ref> 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>PMID:12535064</ref> <ref>PMID:22320386</ref> 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>PMID:12535064</ref> <ref>PMID:22320386</ref> Isoform DeltaLf: transcription factor with antiproliferative properties and inducing cell cycle arrest. Binds to DeltaLf response element found in the SKP1, BAX, DCPS, and SELH promoters.<ref>PMID:12535064</ref> <ref>PMID:22320386</ref>
