FUS

FUS RNA binding protein

NCBI Gene: 2521 Ensembl GeneCards UniProt: P35637

Pathway candidate — not linked to PFS or PSSD by any record here

FUS is in the library because it belongs to the rna processing family. No study, report or commentary in the corpus names it, so a variant in FUS is not, by itself, evidence of anything related to post-drug syndromes.

Gene summary

A protein-coding gene on chromosome 16 (rna processing and mirna biogenesis). Encodes a multifunctional protein component of the heterogeneous nuclear ribonucleoprotein (hnRNP) complex. The hnRNP complex is involved in pre-mRNA splicing and the export of fully processed mRNA to the cytoplasm.

Protein reference (UniProt)

Protein: RNA-binding protein FUS
Function: DNA/RNA-binding protein that plays a role in various cellular processes such as transcription regulation, RNA splicing, RNA transport, DNA repair and damage response. Binds to ssRNA containing the consensus sequence 5'-AGGUAA-3'. Binds to nascent pre-mRNAs and acts as a molecular mediator between RNA polymerase II and U1 small nuclear ribonucleoprotein thereby coupling transcription and splicing. Also binds its own pre-mRNA and autoregulates its expression; this autoregulation mechanism is mediated by non-sense-mediated decay. Plays a role in DNA repair mechanisms by promoting D-loop formation and homologous recombination during DNA double-strand break repair. In neuronal cells, plays crucial roles in dendritic spine formation and stability, RNA transport, mRNA stability and synaptic homeostasis (By similarity).
Subcellular location: Nucleus.
Tissue specificity: Ubiquitous.
Associated conditions: Angiomatoid fibrous histiocytoma (AFH); Amyotrophic lateral sclerosis 6, with or without frontotemporal dementia (ALS6); Tremor, hereditary essential 4 (ETM4).

Why its pathway is in the library

miRNA biogenesis and RNA handling; epigenetic-adjacent regulation with no direct post-drug-syndrome link established.

Written for the whole rna processing family, not for FUS specifically.

Mentioned in 0 corpus records

No corpus record names FUS directly yet. It is in the library because it sits in a pathway the corpus tracks (RNA processing).
