Nup98-HoxA9 is recruited to Hox gene cluster regions together with the chromosomally pre-bound nuclear export factor Crm1, which induces aberrant expression of several Hox genes and affecting the differentiation of embryonic stem cells.

Fibrolamellar carcinoma results from a genetic lesion that produces the DNAJ-PKAc fusion kinase, which is recruited into macromolecular complexes and is sensitive to combinations of signal transduction inhibitor drugs.
Protein kinase A-driven increases in c-MYC protein expression and tumor cell proliferation can be blocked by eIF4A inhibitors, suggesting a potential new treatment option for patients with oncogenic PKA activation.

A minimal subset of two to three residues in cyclic nucleotide binding (CNB) domains controls nucleoside vs. cyclic nucleotide specificity, repurposing PKA of certain pathogens for novel nucleoside signaling pathways or sensing.
MgADP binding to the high-affinity 'consensus' ATPase active site of SUR1 and remodeling of the L0-loop (lasso region) overrides tonic ATP inhibition of KATP channels.
A polarized Moody/protein kinase A pathway plays an unrecognized central role in controlling the enormous cell growth and blood–brain barrier integrity in a highly coordinated spatiotemporal manner in brain homeostasis.
EPO/JAK2/PKA signaling cascade via AKAP10 relocalization to the outer mitochondrial membrane results in the phosphorylation of the terminal heme synthesis enzyme ferrochelatase, which contributes to heme production in red cells.
