Early‐Life Telomere Length Negatively Covaries With Brood Size and Father Age, and Predicts Long‐Term Survival in Male Barn Swallows (Hirundo rustica)

Integrative Zoology, EarlyView.
In barn swallows, nestlings raised in larger broods or by older social fathers have shorter telomeres, and those with longer telomeres tend to live longer, suggesting that early‐life conditions may shape individual lifespan through telomere dynamics. ABSTRACT Parental decisions on breeding, such as brood size and timing of reproduction, influence the ...

Tyrosine kinase LYN restricts the replication and virulence of influenza A virus by directly phosphorylating viral nucleoprotein

mBio
The continuous antigenic shift and drift of influenza A virus (IAV) result in the emergence of novel strains and drug resistance. Accordingly, it is urgent to develop novel antiviral drugs that target host factors.

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Unveiling a Drift Resistant Cryptotope within Marburgvirus Nucleoprotein Recognized by Llama Single-Domain Antibodies

Frontiers in Immunology, 2017
Marburg virus (MARV) is a highly lethal hemorrhagic fever virus that is increasingly re-emerging in Africa, has been imported to both Europe and the US, and is also a Tier 1 bioterror threat.

Effect of Hypophysectomy on Liver Nucleoproteins.

Experimental Biology and Medicine, 1955
SummaryEarlier investigations on liver nucleoprotein changes following hypophysectomy have been extended showing that the DNA per average nucleus is increased. This is not restored to normal values rapidly, since treatment for one week with growth hormone effects no appreciable reduction. These data obtained by chemical analyses strongly indicated that

Human APOBEC3G suppresses homologous recombination and LIG4‐independent end joining in DNA double‐strand break repair

The FEBS Journal, EarlyView.
Chromosomal DNA double‐strand breaks (DSBs) are repaired by homologous recombination and nonhomologous end joining (NHEJ). Recent work has additionally established theta‐mediated end‐joining (TMEJ) as a mechanism for DSB joining. Cells lacking NHEJ and TMEJ can repair DSBs in a homology‐dependent manner.

Phenotypic Consequence of Rearranging the N Gene of RABV HEP-Flury

Viruses, 2019
Nucleoprotein (N) is a key element in rabies virus (RABV) replication. To further investigate the effect of N on RABV, we manipulated an infectious cDNA clone of the RABV HEP-Flury to rearrange the N gene from its wild-type position of 1 (N-P-M-G-L) to 2

The trimeric Shu complex in C. elegans is an ATPase that remodels RAD51 filaments in the homologous recombination‐associated DNA damage response

The FEBS Journal, EarlyView.
The C. elegans Shu complex (RFS‐1/RIP‐1/SWS‐1) is a DNA‐dependent ATPase that regulates RAD‐51 filaments during homologous recombination. The trimer preferentially binds 5′‐exposed DNA, remodels RAD‐51 filaments via ATP hydrolysis, and stabilizes filaments through ATP binding.

Dissociation of nucleoprotein complexes by chaotropic salts [PDF]

, 1983
The effect of various anions in destabilizing yeast nucleoprotein complexes followed the order F− < Cl− < Br− < ClO−4 ⋍ Cl3CCOO−. Treatment of yeast nucleoproteins with 0.5 M NaClO4 resulted in removal of 80% of RNA. Based on the results, a simple method

The PACS-2 protein and trafficking motifs in CCHFV Gn and Gc cytoplasmic domains govern CCHFV assembly

Emerging Microbes and Infections
The Crimean-Congo hemorrhagic fever virus (CCHFV) is a tick-borne bunyavirus that causes high mortality in humans. This enveloped virus harbors two surface glycoproteins (GP), Gn and Gc, that are released by processing of a glycoprotein precursor complex
