Overview of Gene Research
Srpk2, short for serine-arginine protein kinase 2, is a key kinase involved in multiple biological processes. It phosphorylates serine-arginine rich proteins, playing a role in pre-mRNA splicing, which is crucial for gene expression regulation. It is associated with pathways related to lipid metabolism, inflammation, and viral replication, and is of great biological importance as it impacts cell fate, proliferation, and differentiation [3,4,5]. Genetic models such as gene knockout can be valuable for studying its functions.

In HepG2 cells, SRPK2-knockout suppressed the phosphorylation of hepatitis B core protein (Cp), indicating its importance in the HBV life cycle as it mediates Cp phosphorylation and capsid assembly [1]. In BV2 microglia, enhancing SRPK2 expression led to pro-inflammatory activation, while SRPK2 deficiency alleviated the cytotoxic effects of stimuli on HT22 cells, suggesting its role in the inflammatory response in Alzheimer's disease [2]. In FGF21 knockout mice, silencing SRPK2 rescued alcohol-induced splicing dysregulation and liver injury, highlighting its role in alcohol-associated liver disease [4].

In conclusion, Srpk2 is essential for processes like pre-mRNA splicing, viral capsid assembly, microglia activation, and lipogenesis in alcohol-associated liver disease. Gene knockout models have been instrumental in revealing its roles in HBV-related liver diseases, Alzheimer's disease, and alcohol-associated liver disease, providing insights into disease mechanisms and potential therapeutic targets.
