Receptor-specific regulation of phosphatidylinositol 3'-kinase activation by the protein tyrosine phosphatase Shp2 [PDF]

, 2002
Receptor tyrosine kinases (RTKs) play distinct roles in multiple biological systems. Many RTKs transmit similar signals, raising questions about how specificity is achieved.

Requirements for Site-Specific Recombination in the Tyrosine-Family Recombinase Active Site [PDF]

Biophysical Journal, 2014
Tyrosine recombinase (YR) shares the same active site and catalyzes the DNA rearrangement with identical phosphoryl transfer chemistry to topoisomerases IB (TopIBs). In order to find out the function of each residue within conserved catalytic center and what factor dictates the strikingly different kinetic characteristics, in cis for Cre and λ Int and ...

Transposons as Tools for Future Genome Engineering in Yeasts and Filamentous Fungi

Yeast, EarlyView.
Applications of transposon‐based tools for genome engineering in fungi include transposon‐mediated mutagenesis and targeted genomic integration. ABSTRACT Transposons are fundamental genetic elements that have profoundly shaped the architecture of eukaryotic genomes.

Tyrosine phosphorylation of myosin heavy chain during skeletal muscle differentiation: an integrated bioinformatics approach [PDF]

, 2005
Background: Previously it has been shown that insulin-mediated tyrosine phosphorylation of myosin heavy chain is concomitant with enhanced association of C-terminal SRC kinase during skeletal muscle differentiation. We sought to identify putative site(s)

Functional analysis of box I mutations in yeast site-specific recombinases Flp and R: pairwise complementation with recombinase variants lacking the active-site tyrosine. [PDF]

Molecular and Cellular Biology, 1992
The site-specific recombinases Flp and R from Saccharomyces cerevisiae and Zygosaccharomyces rouxii, respectively, are related proteins that belong to the yeast family of site-specific recombinases. They share approximately 30% amino acid matches and exhibit a common reaction mechanism that appears to be conserved within the larger integrase family of ...

An intracellular recombinant single‐chain variable antibody fragment as a new class of phosphodiesterase type 5 inhibitors

British Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a ubiquitous second messenger involved in human (patho‐)physiology. Phosphodiesterase 5 (PDE5) is a major cGMP hydrolyzing enzyme in many cell types including vascular smooth muscle cells (VSMCs). Several highly selective PDE5 inhibitors are in clinical use. However, there are currently no

Image_8_In vitro DNA Inversions Mediated by the PsrA Site-Specific Tyrosine Recombinase of Streptococcus pneumoniae.TIF

, 2020
Site-specific recombination is a DNA breaking and reconstructing process that plays important roles in various cellular pathways for both prokaryotes and eukaryotes. This process requires a site-specific recombinase and direct or inverted repeats.

Long non‐coding RNAs at the crossroads of inflammation, cancer and angiogenesis: Molecular mechanisms and their potential as therapeutic targets

British Journal of Pharmacology, EarlyView.
Long non‐coding RNAs (lncRNAs), a broad class of non‐protein‐coding RNAs, are characterized as new regulators of gene expression at the epigenetic, transcriptional, and post‐transcriptional level. Thus, lncRNAs are involved in the regulation of physiological processes and the development of human diseases and cancer by modulating proinflammatory ...

Structure-function analysis of IntDOT, the CTnDOT integrase [PDF]

, 2010
IntDOT is an enzyme required for the recombination reactions that promote movement of CTnDOT that is an integrative conjugative element (ICE) found in Bacteroides spp. IntDOT has been classified in the tyrosine recombinase family.

EGF regulates tyrosine phosphorylation and membrane-translocation of the scaffold protein Tks5 [PDF]

, 2013
Background: Tks5/FISH is a scaffold protein comprising of five SH3 domains and one PX domain. Tks5 is a substrate of the tyrosine kinase Src and is required for the organization of podosomes/invadopodia implicated in invasion of tumor cells.
