PIPPIN, also known as CSDC2 (Cold shock domain-containing protein C2) is an RNA‐binding protein (RBP), highly enriched in the rat brain, specifically enriched in some pyramidal neurons of the cerebral cortex and in the Purkinje cells of the cerebellum (PMID: 10446180). PIPPIN has the potential to undergo different posttranslational modifications and might be a good candidate to regulate the synthesis of specific proteins in response to extracellular stimuli. Nuclear CSDC2 is connected to proliferation and cytoplasmic CSDC2 to terminal differentiation in the decidua and that CSDC2 could regulate differentiation during decidua development (PMID: 30078185, PMID: 17053029).
