Fused in sarcoma (FUS), also called translocated in liposarcoma (TLS), is a ubiquitously expressed DNA/RNA binding protein belonging to the TET family and predominantly localized in the nucleus. FUS is proposed to be involved in various RNA metabolic pathways including transcription regulation, nucleo-cytosolic RNA transport, microRNA processing or pre-mRNA splicing [1]. Mutations in the FUS gene were identified in patients with familial amyotrophic lateral sclerosis (ALS) type 6 and sporadic ALS [2, 3]. ALS, also termed Lou Gehrig's disease, is a fatal adult-onset neurodegenerative disease affecting upper and lower motor neurons in the brain and spinal cord. There is increasing evidence supporting the hypothesis that FUS might play an important role in pre-mRNA splicing regulation. Several splicing factors were identified to associate with FUS including hnRNPA2 and C1/C2 [4], Y-box binding protein 1 (YB-1) [5] and serine arginine (SR) proteins (SC35 and TASR) [6]. Additionally, FUS was identified as a constituent of human spliceosomal complexes [1]. Our recent results indicate that FUS has increased affinity for certain but not all snRNPs of the minor and major spliceosome. Furthermore, in vitro studies revealed that FUS directly interacts with a factor specific for one of those snRNPs. These findings might uncover the molecular mechanism by which FUS regulates splicing and could explain previously observed effects of FUS on the splicing of the adenovirus E1A minigene [7] and changes in splicing caused by ALS associated FUS mutations.
