HAPLN1: Proteins and Enzymes

HAPLN1 (also known as link protein and CRTL1) is a member of the hyaladherin family of hyaluronic acid (HA) binding proteins. Hyaluronan binding proteins are of two types; those with link modules, and those without. Link modules are 100 amino acid (aa) HA and protein-binding sequences that contain two alpha-helices and two anti-parallel beta-sheets. There are three categories of link module-containing proteins. 'A' domain-type proteins contain one link module; 'B' domain-type proteins contain ...
