Cap and cap‐binding proteins in the control of gene expression

WIREs RNA, 2010
AbstractThe 5′ mRNA cap structure is essential for efficient gene expression from yeast to human. It plays a critical role in all aspects of the life cycle of an mRNA molecule. Capping occurs co‐transcriptionally on the nascent pre‐mRNA as it emerges from the RNA exit channel of RNA polymerase II.

F-actin capping proteins

Current Opinion in Cell Biology, 1993
Recent research on F-actin capping proteins has concentrated on three main areas. The discovery that controlled actin polymerization is the driving force for intracellular movement suggests an important role for capping proteins in regulating filament number and length. A capping protein from Dictyostelium (related to heat-shock protein HSP70) has been

Capping protein

1999
Abstract Capping protein (CP) is a heterodimeric actin-binding protein found in all eukaryotic cells (reviewed in ref. 1). In vitro, CP binds tightly to the barbed ends of actin filaments, nucleates polymerization of actin and is inhibited by PIP2.

Differential stimulation of capped mRNA translation in vitro by cap binding protein

Nature, 1980
The cap structure, m7GpppN, which is present at the 5′ end of most eukaryotic mRNAs, facilitates the initiation of protein synthesis1. Rabbit reticulocytes and mouse L and ascites cells have been shown to contain a protein (molecular weight (MW) 24,000) that specifically recognizes the cap of reovirus mRNA and several other capped mRNAs2.

Cap-recognizing protein of influenza virus

Virology, 1982
Abstract Globin mRNA-primed in vitro transcription of influenza virus is inhibited by m 7 GpppGm, m 7 GpppG, and m 7 GTP indicating that the cap analogs block the specific binding site involved in the cap transfer reaction. γ-[4-(Benzoylphenyl)methylamido]-7-methylguanosine-5′-triphosphate, a photoreactive derivative of m 7 GTP, was used as an ...

Transcription activation by catabolite activator protein (CAP)

Journal of Molecular Biology, 1999
Transcription activation by Escherichia coli catabolite activator protein (CAP) at each of two classes of simple CAP-dependent promoters is understood in structural and mechanistic detail. At class I CAP-dependent promoters, CAP activates transcription from a DNA site located upstream of the DNA site for RNA polymerase holoenzyme (RNAP); at these ...

Protein Capping and Nanoparticles

2018
Nanoparticles have distinct properties and these properties are rapidly revolutionizing the biomedical applications. Despite of development in nanoscience, there is quite little understanding about the interaction of nanomaterials with living systems for the safe and proficient application.
