Lactoferrin
FunctionLactoferrin or lactotransferrin (LTF) is found in secretory fluids. LTF interacts with DNA, RNA, polysaccharides and heparin[1]. For detailed discussion of human lactoferrin see Human lactoferrin. RelevanceLTF is inhibited by nonsteroidal anti-inflammatory drugs (NSAID) like aspirin. It is a component of the immune system and has antimicrobial activity[2]. LTF can be used as a marker for inflammatory bowel disease[3]. Structural highlightsLTF is a bilobal protein with the . LTF binds with high affinity Fe+3 ion and an anion in both its N-lobe and its C-lobe[4]. The binding site is between the 2 domains of each lobe. . The . . The .
