Structure of selected human lipocalins. Human α1-microglobulin (A1M), retinol binding protein 4 (RBP4), lipocalin 2 (LCN2), and lipocalin-type PGD2 synthase protein (L-PGDS) all share a highly similar structure with a typical eight-stranded, antiparallel symmetrical β-barrel fold. The structures of the discussed lipocalins were created using Ribbons XP software (version 3.0) and the coordinates 3QKG, 2WQ9, 3U0D, and 4ORS deposited in the RCSB Protein Data Bank (http://www.rcsb.org, accessed 6 April 2024).
