In mature skeletal muscle, in vivo PKN2 knockdown decreased glucose uptake and increased AMPK phosphorylation. Thus, PKN2 alters key signaling pathways and transcriptional networks to regulate glucose and lipid metabolism.

Mechanistically, Yersinia pseudotuberculosis YopM recruits and activates the mouse host kinases PRK1 and PRK2 to negatively regulate pyrin by phosphorylation.

PKN2 formed complexes with Cdo, APPL1 and AKT via its C-terminal region and this interaction appeared to be important for induction of AKT activity as well as myoblast differentiation.
Title: PKN2 and Cdo interact to activate AKT and promote myoblast differentiation.
To unravel the in vivo physiological function of PKN2, we targeted the PKN2 gene. Constitutive disruption of the mouse PKN2 gene resulted in growth retardation and lethality before embryonic day (E) 10.5. PKN2(-/-) embryo did not undergo axial turning and showed insufficient closure of the neural tube.Mouse embryonic fibroblasts (MEFs) derived from PKN2(-/-) embryos at E9.5 failed to grow.
Title: PKN2 is essential for mouse embryonic development and proliferation of mouse fibroblasts.
Yersinia pseudotuberculosis mutants expressing YopM proteins unable to interact with either RSK1 or PRK2 were defective for virulence in this assay, indicating that both interaction domains are important for YopM to promote pathogenesis.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
