SFPQ also known as splicing factor proline and glutamine-rich (PSF) is a multifunctional protein serving in various cellular processes. The protein weighs approximately 76 kDa and is ubiquitously expressed across different tissues. It mainly localizes in the nucleus where it interacts with RNA and other proteins. SFPQ plays essential roles in RNA splicing and transcription regulation among others.
Biological function summary
SFPQ takes part in multiple cellular processes including RNA processing gene expression regulation and DNA repair. SFPQ forms complexes with other proteins such as NONO which enhances its ability in transcriptional control and RNA splicing. By binding to DNA and RNA SFPQ acts as a bridge that connects various molecular events important for cell function and survival.
Pathways
The protein is actively involved in the modulation of RNA metabolic pathways and signal transduction. In particular SFPQ participates in the regulation of alternative splicing processes which can influence the diversity of the proteome. Functionally related proteins like FUS show interactions with SFPQ within these pathways jointly affecting gene expression dynamics.
Aberrations in SFPQ expression or function associate with neurodegenerative diseases and cancers. Mislocalization of SFPQ and its altered expression have been observed in conditions like amyotrophic lateral sclerosis (ALS) and certain leukemia types. In these disorders proteins like TDP-43 have shown associations with SFPQ contributing to the pathology through disrupted RNA processing and cellular stress responses.
