Function

edit

This gene encodes a member of the lysyl oxidase gene family. The prototypic member of the family is essential to the biogenesis of connective tissue, encoding an extracellular copper-dependent amine oxidase that catalyses the first step in the formation of crosslinks in collagens and elastin. A highly conserved amino acid sequence at the C-terminus end appears to be sufficient for amine oxidase activity, suggesting that each family member may retain this function. The N-terminus is poorly conserved and may impart additional roles in developmental regulation, senescence, tumor suppression, cell growth control, and chemotaxis to each member of the family.[4]

Clinical significance

edit

Polymorphisms of the LOXL1 gene are associated with pseudoexfoliation syndrome, a disease where the extracellular matrix contains abnormal amounts of cross-linked, amyloid-like fibrillar material and glycoproteins. When this happens in the eye, exfoliation glaucoma results.[6][7]

Interactions

edit

LOXL1 has been shown to interact with FBLN5.[8]
