Structural highlights
Disease[FUS_HUMAN] Frontotemporal dementia with motor neuron disease;Hereditary essential tremor;Amyotrophic lateral sclerosis;Juvenile amyotrophic lateral sclerosis;Myxofibrosarcoma;Myxoid/round cell liposarcoma. A chromosomal aberration involving FUS is found in a patient with malignant myxoid liposarcoma. Translocation t(12;16)(q13;p11) with DDIT3. A chromosomal aberration involving FUS is a cause of acute myeloid leukemia (AML). Translocation t(16;21)(p11;q22) with ERG. The disease may be caused by mutations affecting the gene represented in this entry. A chromosomal aberration involving FUS is found in a patient with angiomatoid fibrous histiocytoma. Translocation t(12;16)(q13;p11.2) with ATF1 generates a chimeric FUS/ATF1 protein. The disease is caused by mutations affecting the gene represented in this entry. The disease is caused by mutations affecting the gene represented in this entry. Function[FUS_HUMAN] Binds both single-stranded and double-stranded DNA and promotes ATP-independent annealing of complementary single-stranded DNAs and D-loop formation in superhelical double-stranded DNA. May play a role in maintenance of genomic integrity. Publication Abstract from PubMedFused in sarcoma (FUS) is an RNA binding protein involved in regulating many aspects of RNA processing and linked to several neurodegenerative diseases. Transcriptomics studies indicate that FUS binds a large variety of RNA motifs, suggesting that FUS RNA binding might be quite complex. Here, we present solution structures of FUS zinc finger (ZnF) and RNA recognition motif (RRM) domains bound to RNA. These structures show a bipartite binding mode of FUS comprising of sequence-specific recognition of a NGGU motif via the ZnF and an unusual shape recognition of a stem-loop RNA via the RRM. In addition, sequence-independent interactions via the RGG repeats significantly increase binding affinity and promote destabilization of structured RNA conformation, enabling additional binding. We further show that disruption of the RRM and ZnF domains abolishes FUS function in splicing. Altogether, our results rationalize why deciphering the RNA binding mode of FUS has been so challenging.
