Function

Siderocalin (Scn) or neutrophil gelatinase-associated lipocalin binds ferric siderophores in order to intercept delivery of iron to bacteria which require it thus impeding their virulence[1].

Relevance

Scn-NGAL levels are markedly upregulated by tissue damage. Scn-NGAL is derived from damaged kidneys. The presence of Scn-NGAL in serum or urine anticipates a severe course for the patient including the need for dialysis and the possibility of death[2].

Structural highlights

Scn-NGAL interacts with the making [3]. Water molecules are shown as red spheres. .
