            Figure 2. Function of paraspeckles in the transcription and splicing of mRNAs. The splicing factors NONO and SFPQ assemble with NEAT1_2 and then
            associate with PSPC1, HNRNPK, HNRNPA1, FUS, and RBM14, forming the NEAT1_2 ribonucleoprotein (RNP) complex. Image created by the authors
