The Survival of Motor Neuron Protein Acts as a Molecular Chaperone for mRNP Assembly

open access: yesCell Reports, 2017
Spinal muscular atrophy (SMA) is a motor neuron disease caused by reduced levels of the survival of motor neuron (SMN) protein. SMN is part of a multiprotein complex that facilitates the assembly of spliceosomal small nuclear ribonucleoproteins (snRNPs).

The Ribosome Cooperates with the Assembly Chaperone pICln to Initiate Formation of snRNPs

open access: yesCell Reports, 2016
The formation of macromolecular complexes within the crowded environment of cells often requires aid from assembly chaperones. PRMT5 and SMN complexes mediate this task for the assembly of the common core of pre-mRNA processing small nuclear ...

Schizophrenia gene networks and pathways and their applications for novel candidate gene selection. [PDF]

open access: yesPLoS ONE, 2010
Schizophrenia (SZ) is a heritable, complex mental disorder. We have seen limited success in finding causal genes for schizophrenia from numerous conventional studies.

Negative cooperativity between Gemin2 and RNA provides insights into RNA selection and the SMN complex's release in snRNP assembly

open access: yesbioRxiv, 2018
The assembly of snRNP cores, in which seven Sm proteins, D1/D2/F/E/G/D3/B, form a ring around the nonameric Sm site of snRNAs, is the early step of spliceosome formation and essential to eukaryotes.

Self-oligomerization regulates stability of survival motor neuron protein isoforms by sequestering an SCFSlmb degron [PDF]

open access: yes, 2017
Spinal muscular atrophy (SMA) is caused by homozygous mutations in human SMN1. Expression of a duplicate gene (SMN2) primarily results in skipping of exon 7 and production of an unstable protein isoform, SMNΔ7.

The Cajal body protein p80-coilin forms a complex with the adenovirus L4-22K protein and facilitates the nuclear export of adenovirus mRNA

open access: yesmBio, 2023
Cajal bodies (CBs) are major sub-nuclear structures in most eucaryotic cells. In human adenovirus 5 (Ad5) infection, CBs are reorganized into microfoci in the late phase of infection.

A U1 snRNP-Specific Assembly Pathway Reveals the SMN Complex as a Versatile RNP Exchange

open access: yesNature Structural &Molecular Biology, 2016
Despite equal snRNP stoichiometry in spliceosomes, U1 snRNP (U1) is typically the most abundant vertebrate snRNP. Mechanisms regulating U1 overabundance and snRNP repertoire are unknown.

Phosphatase and tensin homologue: a therapeutic target for SMA [PDF]

open access: yes, 2017
Spinal muscular atrophy (SMA) is one of the most common juvenile neurodegenerative diseases, which can be associated with child mortality. SMA is caused by a mutation of ubiquitously expressed gene, Survival Motor Neuron1 (SMN1), leading to reduced SMN ...

Toward an assembly line for U7 snRNPs: interactions of U7-specific Lsm proteins with PRMT5 and SMN complexes.

open access: yesThe Journal of biological chemistry, 2005
The survival of motor neurons (SMN) complex mediates the assembly of small nuclear ribonucleoproteins (snRNPs) involved in splicing and histone RNA processing. A crucial step in this process is the binding of Sm proteins onto the SMN protein. For Sm B/B', D1, and D3, efficient binding to SMN depends on symmetrical dimethyl arginine (sDMA) modifications

GEMINs: Potential Therapeutic Targets for Spinal Muscular Atrophy?

open access: yesFrontiers in Neuroscience, 2014
The motor neuron degenerative disease spinal muscular atrophy (SMA) remains one of the most frequently inherited causes of infant mortality. Afflicted patients loose the survival motor neuron 1 (SMN1) gene but retain one or more copies of SMN2, a ...
