LOXL2 (lysyl oxidase like 2) is an amino oxidase which is dependent on copper and quinone. LOXL2 participates in various events, such as gene transcription, cell migration, adhesion, angiogenesis and differentiation. It is responsible for connecting collagen and/or elastin in the extracellular matrix. It deaminates trimethylated lysine 4 in histone H3, causing transcriptional repression. LOXL2 also oxidises methylated TAF10 (TATA-box binding protein associated factor 10), suppressing some TFIID (transcription factor IID)-associated genes. The LOXL2 gene is upregulated in various cancers, such as gastric cancer, breast cancer and squamous cell carcinomas. The gene is associated with cancer cell invasion, lymph node metastasis and poor overall patient survival.
