Background: HAPLN4

Hyaluronan and Proteoglycan Link Protein 4, (HAPLN4), also known as brain link protein 2, is one of four secreted HAPLN family proteoglycans that bind hyaluronan. HAPLN4 contains one Ig-type C2-set domain and two link domains. It is predominantly expressed in brain and participates in the development of the perineuronal matrix. Human and mouse HAPLN4 share 91% aa sequence identity.
