Methylation of lysine 4 (K4) within histone H3 has been linked to active transcription and is removed by LSD1 and the JmjC domain-containing proteins by amino-oxidation or hydroxylation, respectively. Here, we describe the deamination catalyzed by Lysyl oxidase-like 2 protein (LOXL2) as an unconventional chemical mechanism for H3K4 modification. Infrared spectroscopy and mass spectrometry analyses demonstrated that recombinant LOXL2 specifically deaminates trimethylated H3K4. Moreover, LOXL2 activity is linked with the transcriptional control of CDH1 gene by regulating H3K4me3 deamination. These results reveal another H3 modification and provide a different mechanism for H3K4 modification.

Alzheimer's disease (AD) is the most prevalent neurodegenerative dementia, marked by progressive cognitive decline and memory impairment. Despite advances in therapeutic research, single-target-directed treatments often fall short in addressing the complex, multifactorial nature of AD. This arises from various pathological features, including amyloid-β (Aβ) aggregate deposition, metal ion dysregulation, oxidative stress, impaired neurotransmission, neuroinflammation, mitochondrial dysfunction, and neuronal cell death.

Background: Lysyl oxidase-like 2 (LOXL2) is a metalloenzyme that catalyzes oxidative deamination ε-amino group of lysine. It has been found that LOXL2 is a promotor for the metastasis and invasion in kinds of tumors. Previous studies show that disulfide bonds are important components in LOXL2, and their bioactivity can be regulated by those bonds.

Abdominal aortic aneurysm (AAA) is a common, progressive and potentially fatal dilation of the most distal aortic segment. Multiple studies with longitudinal follow-up of AAA have identified markedly slower progression among patients affected with diabetes. Understanding the molecular pathway responsible for the growth inhibition could have implications for therapy in nondiabetic AAA patients.
