PDE4DIP and sarcoidosis: Finally, PDE4DIP (phosphodiesterase 4D interacting protein or myomegalin), whose gene was found to be frequently mutated in familial cases of sarcoidosis, interacts with SARS-CoV2 protein NSP13 and should be considered due to its close interaction with phosphodiesterase 4D, which is anchored at the centrosome-Golgi region and plays a functional role in microtubule formation [76].
