Anomalous HIV-1 RNA, How Cap-Methylation Segregates Viral Transcripts by Form and Function

Viruses, 2022
The acquisition of m7G-cap-binding proteins is now recognized as a major variable driving the form and function of host RNAs. This manuscript compares the 5′-cap-RNA binding proteins that engage HIV-1 precursor RNAs, host mRNAs, small nuclear (sn)- and ...

Abnormal motoneuron migration, differentiation, and axon outgrowth in spinal muscular atrophy [PDF]

, 2008
The role of heterotopic (migratory) motoneurons (HMN) in the pathogenesis of spinal muscular atrophy (SMA) is still controversial. We examined the occurrence and amount of HMN in spinal cord tissue from eight children with SMA (six with SMA-I and two ...

Domain associated with zinc fingers‐containing NF90‐NF45 complex inhibits m6A modification of primary microRNA by suppressing METTL3/14 activity

FEBS Open Bio, EarlyView.
NF90–NF45 functions as a negative regulator of methyltransferase‐like 3/14 (METTL3/14)‐mediated N6‐methyladenosine (m6A) modification on primary microRNAs (pri‐miRNAs). NF90–NF45 binds to anti‐oncogenic pri‐miRNAs and inhibits their m6A modification, thereby suppressing the biogenesis of anti‐oncogenic miRNAs.

UsnRNP trafficking is regulated by stress granules and compromised by mutant ALS proteins

Neurobiology of Disease, 2020
Activation of the integrated stress response (ISR), alterations in nucleo-cytoplasmic (N/C) transport and changes in alternative splicing regulation are all common traits of the pathogenesis of Amyotrophic Lateral Sclerosis (ALS).

Host Factors interacting with the Pestivirus N terminal protease, Npro are Components of the Ribonucleoprotein Complex [PDF]

, 2014
The viral N-terminal protease N(pro) of pestiviruses counteracts cellular antiviral defenses through inhibition of IRF3. Here we used mass spectrometry to identify a new role for N(pro) through its interaction with over 55 associated proteins, mainly ...

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Single molecule analysis reveals reversible and irreversible steps during spliceosome activation

eLife, 2016
The spliceosome is a complex machine composed of small nuclear ribonucleoproteins (snRNPs) and accessory proteins that excises introns from pre-mRNAs.

Comparative interactomics provides evidence for functional specialization of the nuclear pore complex [PDF]

, 2017
The core architecture of the eukaryotic cell was established well over one billion years ago, and is largely retained in all extant lineages. However, eukaryotic cells also possess lineage-specific features, frequently keyed to specific functional ...

Small nuclear RNAs and small nuclear ribonucleoprotein complexes purified from the feline placenta.

The Japanese Journal of Veterinary Science, 1986
Small nuclear RNAs (snRNAs) and small nuclear ribonucleoprotein particles (snRNPs) were purified from the cat placenta as an initial step in the analysis of the regulatory mechanism(s) of gene expression in the placenta. For visual observations, snRNA species including 7S, U2, U1, U4, X-I, X-II, 5S, U5, U6 and X-III were stained with acrydine orange ...

SNUPN‐Related Muscular Dystrophy: Novel Phenotypic, Pathological and Functional Protein Insights

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective SNUPN‐related muscular dystrophy or LGMDR29 is a new entity that covers from a congenital or childhood onset pure muscular dystrophy to more complex phenotypes combining neurodevelopmental features, cataracts, or spinocerebellar ataxia. So far, 12 different variants have been described.
