To test whether cytoplasmic hnRNPA2 protein is also functionally relevant in PCa, we employed an ectopic expression vector encoding an HA-tagged hnRNPA2 mutant containing a deletion (R191-G253) of the RGG domain (hnRNPA2-ΔRGG), which is exclusively expressed in the cytoplasm.4 This evidence concerns the gene HNRNPA2B1 and posterior cortical atrophy.
