Lysyl Oxidase Homolog 3/LOXL3: ELISA Kits

Lysyl oxidase-like protein 3 (LOXL3) is a secreted copper amine oxidase. The N-terminal region of LOXL3 contains four scavenger receptor cysteine-rich (SRCR) domains. The C-terminal region consists of a catalytic domain similar to other lysyl oxidases and a cytokine receptor-like domain. The catalytic domain contains conserved residues required for copper binding and formation of a lysyl tyrosylquinone cofactor. LOXL3 is expressed primarily in epidermis, kidney, aorta, and chondrocytes. The enzyme is expressed at low levels in most other tissues. Like lysyl oxidase, LOXL3 oxidizes the lysine e-amino groups of a number of collagen substrates, and is also active against other primary amines. However, LOXL3 does not require proteolytic processing to be activated.
