polypyrimidine tract-binding protein-associated splicing factor
PSF: nuclear busy-body or nuclear facilitator?
Philadelphia, United States. In Wiley Interdiscip Rev Rna, Jul 2015
PTB-associated splicing factor (PSF) is an abundant and essential nucleic acid-binding protein that participates in a wide range of gene regulatory processes and cellular response pathways.
A molecular mechanism for circadian clock negative feedback.
Boston, United States. In Science, 2011
analysis indicates PSF within the PER complex recruits SIN3A, a scaffold for assembly of transcriptional inhibitory complexes, and the PER complex thereby rhythmically delivers histone deacetylases to the Per1 promoter, which repress Per1 transcription

They are RNA-protein structures formed by the interaction between a long nonprotein-coding RNA species, NEAT1/Men epsilon/beta, and members of the DBHS (Drosophila Behavior Human Splicing) family of proteins: P54NRB/NONO, PSPC1, and PSF/SFPQ.
