Ulk3, or unc-51 like kinase 3, is a serine/threonine protein kinase involved in multiple cellular processes. It plays crucial roles in autophagy, cell division, and regulation of the Sonic hedgehog pathway. It also has functions in the context of epigenetic regulation, being involved in histone arginine methylation, which is important for epidermal homeostasis and oncogenesis [1].

In keratinocytes and SCC-derived cells, gene silencing or deletion of Ulk3 reduces proliferation and clonogenicity, and affects transcription related to stem cell-related and metabolism programs [1]. In BIN1-deficient mouse hippocampal neurons, reducing Ulk3 activity mitigates dendritic regression, hippocampal volume loss, and spatial memory decline [2]. In breast cancer, Mendelian randomization analysis associated Ulk3 with the disease [3]. In epilepsy, a Mendelian randomization study found that increased Ulk3 levels were associated with a decreased risk of focal epilepsy [4].

In summary, Ulk3 is essential for multiple cellular processes such as autophagy and cell division. Model-based research, including gene-silencing experiments in cell lines and in vivo studies in mice, has revealed its roles in various disease conditions like cancer and neurological disorders. These findings contribute to understanding the underlying mechanisms of these diseases and may provide potential therapeutic targets.
