Non-Catalytic Participation of the Pin1 Peptidyl-Prolyl Isomerase Domain in Target Binding

Frontiers in Physiology, 2013
Pin1 is a phosphorylation-dependent peptidyl-prolyl isomerase that has the potential to add an additional level of regulation within protein kinase mediated signaling pathways.

SLiM on Diet: finding short linear motifs on domain interaction interfaces in Protein Data Bank

Bioinformatics, 2010
Abstract Motivation: An important class of protein interactions involves the binding of a protein's domain to a short linear motif (SLiM) on its interacting partner. Extracting such motifs, either experimentally or computationally, is challenging because of their weak binding and high degree of degeneracy.

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

SRC Homology 2 Domain Binding Sites in Insulin, IGF-1 and FGF receptor mediated signaling networks reveal an extensive potential interactome

Cell Communication and Signaling, 2012
Specific peptide ligand recognition by modular interaction domains is essential for the fidelity of information flow through the signal transduction networks that control cell behavior in response to extrinsic and intrinsic stimuli.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

A transient homotypic interaction model for the influenza A virus NS1 protein effector domain [PDF]

, 2011
Influenza A virus NS1 protein is a multifunctional virulence factor consisting of an RNA binding domain (RBD), a short linker, an effector domain (ED), and a C-terminal 'tail'. Although poorly understood, NS1 multimerization may autoregulate its actions.

Mapping and characterization of the interaction interface between two polypyrimidine-tract binding proteins and a nova-type protein of Solanum tuberosum. [PDF]

PLoS ONE, 2013
Polypyrimidine tract-binding (PTB) proteins are RNA-binding proteins that generally contain four RNA recognition motifs (RRMs). In potato, six cDNAs encoding full-length PTB proteins have been identified.

Novel conserved sequence motifs in plant G-box binding proteins and implications for interactive domains

Nucleic Acids Research, 1994
The G-box is a cis-acting DNA sequence present in several plant promoters that are regulated by diverse signals such as UV irradiation, anaerobiosis, abscissic acid and light. Several basic/leucine zipper (bZIP) proteins from different plant species have been identified as high affinity G-box binding proteins.

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
