pfam00061: Lipocalin (this model, PSSM-Id:278490 is obsolete and has been replaced by 395015)
Lipocalin / cytosolic fatty-acid binding protein family
Lipocalins are transporters for small hydrophobic molecules, such as lipids, steroid hormones, bilins, and retinoids. The family also encompasses the enzyme prostaglandin D synthase (EC:5.3.99.2). Alignment subsumes both the lipocalin and fatty acid binding protein signatures from PROSITE. This is supported on structural and functional grounds. The structure is an eight-stranded beta barrel.
