CRYSTAL STRUCTURE OF COPPER-AND OXALATE-SUBSTITUTED HUMAN LACTOFERRIN AT 2.0 ANGSTROMS RESOLUTIONCRYSTAL STRUCTURE OF COPPER-AND OXALATE-SUBSTITUTED HUMAN LACTOFERRIN AT 2.0 ANGSTROMS RESOLUTION
Structural highlights
FunctionTRFL_HUMAN Transferrins are iron binding transport proteins which can bind two Fe(3+) ions in association with the binding of an anion, usually bicarbonate.[1] [2] Lactotransferrin has antimicrobial activity which depends on the extracellular cation concentration.[3] [4] 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.[5] [6] 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.[7] [8] 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.[9] [10] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. See AlsoReferences
