YIPFα1A expression is regulated by multilayered molecular mechanisms

FEBS Open Bio, EarlyView.
YIPFα1A, a five‐pass Golgi protein, is regulated at multiple layers. (1) Rare‐codon enrichment drives translation‐coupled mRNA decay. (2) A proximal 3′‐UTR element stabilizes mRNA. (3) A distal 3′‐UTR element included by alternate poly(A) site usage represses translation, which can be overridden by the proximal 3′‐UTR element.

Engineered dityrosine-bonding of the RSV prefusion F protein imparts stability and potency advantages

Nature Communications
Viral fusion proteins facilitate cellular infection by fusing viral and cellular membranes, which involves dramatic transitions from their pre- to postfusion conformations.

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

FEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

IFITM Genes, Variants, and Their Roles in the Control and Pathogenesis of Viral Infections

Frontiers in Microbiology, 2019
Interferon-induced transmembrane proteins (IFITMs) are a family of small proteins that localize in the plasma and endolysosomal membranes. IFITMs not only inhibit viral entry into host cells by interrupting the membrane fusion between viral envelope and ...

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

FEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Putative Fusion-Associated Small Transmembrane (FAST) Proteins Encoded by Viruses of Pistolviridae, Order Ghabrivirales, Identified from In Silico Analyses

Viruses
Fusion-associated small transmembrane (FAST) proteins are viral nonstructural proteins known to be encoded by specific members of the Spinareoviridae, specifically within the Aquareovirus and Orthoreovirus genera.

Versatile vector tools for efficient protein screening across multiple expression systems

FEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Zyxin restricts viral fusion and entry across multiple virus families

Journal of Virology
The entry of enveloped viruses into host cells requires fusion of the viral envelope with a host cell membrane. The composition and dynamics of cellular membranes are impacted by the underlying cytoskeleton.

Mutagenesis of the fusion peptide-like domain of hepatitis C virus E1 glycoprotein: involvement in cell fusion and virus entry

Journal of Biomedical Science, 2009
Background Envelope (E) glycoprotein E2 of the hepatitis C virus (HCV) mediates binding of the virus to target cell receptors. Nevertheless, the precise role of E1 in viral entry remains elusive.

Low-pH induced conformational changes in viral fusion proteins: implications for the fusion mechanism

Journal of General Virology, 1995
Introduction. Entry of enveloped viruses into host cells requires binding of the virus to one or more receptors present at the host cell surface followed by fusion of the viral envelope with a cellular membrane. After binding, viruses such as paramyxoviruses, retroviruses and herpesviruses are thought to fuse directly with the plasma membrane.
