Defining DYRKs interactome: approaches for the characterization of proximity-dependent interactions and identification of direct substrates
Dual-specificity tyrosine-regulated kinases (DYRKs) are a conserved family of protein kinases present in all eukaryotes. In mammals, the association of DYRKs with a wide variety of putative substrates and interactors, in ...
