Fig. 3From: Update on the human and mouse lipocalin (LCN) gene family, including evidence the mouse Mup cluster is result of an “evolutionary bloom”Structure of prototypical mouse urinary protein. The crystal structure consists of eight β-strands, forming a calyx-shaped barrel (red); this encloses an internal ligand-binding site. There are also an α-helix (green) and four 310-helices (blue); the hydrophobic pocket is located inside the barrel. AB, BC, CD, DE, EF, FG, GH, HI, AND βI denote the amino-acid segments between the β-strands (This diagram taken from Ref. [95])Back to article page
