abstract = {The fragile X protein (FXP) family comprises the
multifunctional RNA-binding proteins FMR1, FXR1, and FXR2
that play an important role in RNA metabolism and regulation
of translation, but also in DNA damage and cellular stress
responses, mitochondrial organization, and more. FMR1 is
well known for its implication in neurodevelopmental
diseases. Recent evidence suggests substantial contribution
of this protein family to amyotrophic lateral sclerosis
(ALS) pathogenesis. ALS is a highly heterogeneous
neurodegenerative disease with multiple genetic and unclear
environmental causes and very limited treatment options. The
loss of motoneurons in ALS is still poorly understood,
especially because pathogenic mechanisms are often
restricted to patients with mutations in specific causative
genes. Identification of converging disease mechanisms
evident in most patients and suitable for therapeutic
intervention is therefore of high importance. Recently,
deregulation of the FXPs has been linked to pathogenic
processes in different types of ALS. Strikingly, in many
cases, available data points towards loss of expression
and/or function of the FXPs early in the disease, or even at
the presymptomatic state. In this review, we briefly
introduce the FXPs and summarize available data about these
proteins in ALS. This includes their relation to TDP-43,
FUS, and ALS-related miRNAs, as well as their possible
contribution to pathogenic protein aggregation and defective
RNA editing. Furthermore, open questions that need to be
addressed before definitively judging suitability of these
proteins as novel therapeutic targets are discussed.},
