ALPK3 Functions as a Pseudokinase.

The article discusses the ALPK3 gene and its potential role in cardiomyopathies. While there are conflicting findings regarding ALPK3's kinase activity, recent studies suggest that ALPK3 functions as a pseudokinase rather than a true kinase. The article presents evidence from in vitro and in vivo experiments, including an in vitro phosphorylation assay and the generation of knock-in mice with a mutated ALPK3 gene. These findings suggest that ALPK3 variants associated with cardiomyopathy may affect other aspects of the protein rather than its kinase activity. [Extracted from the article]
