40LoVe and Samba are involved in Xenopusneural development and functionally distinct from hnRNP AB
(2014)Heterogeneous nuclear ribonucleoproteins (hnRNPs) comprise a large group of modular RNA-binding proteins classified according to their conserved domains. This modular nature, coupled with a large choice of alternative ...

Addressing the Functional Determinants of FAK during Ciliogenesis in Multiciliated Cells
(2017)We previously identified focal adhesion kinase (FAK) as an important regulator of ciliogenesis in multiciliated cells. FAK and other focal adhesion (FA) proteins associate with the basal bodies and their striated rootlets ...

Arginine methylation at histone H3R2 controls deposition of H3K4 trimethylation
(2007)Modifications on histones control important biological processes through their effects on chromatin structure. Methylation at lysine 4 on histone H3 (H3K4) is found at the 5′ end of active genes and contributes to ...

Computational protein design with a generalized born solvent model: Application to asparaginyl-tRNA synthetase
(2011)Computational Protein Design (CPD) is a promising method for high throughput protein and ligand mutagenesis. Recently, we developed a CPD method that used a polar-hydrogen energy function for protein interactions and a ...

Drosophila immune priming against Pseudomonas aeruginosa is short-lasting and depends on cellular and humoral immunity
(2013)Immune responses are traditionally divided into the innate and the adaptive arm, both of which are present in vertebrates, while only the innate arm is found in invertebrates. Immune priming experiments in Drosophila ...

Ets2 is necessary in trophoblast for normal embryonic anteroposterior axis development
(2006)Although the trophoblast is necessary for the growth, viability and patterning of the mammalian embryo, understanding of its patterning role is still rudimentary. Expression of the transcription factor Ets2 is restricted ...

Article
Hedgehog restricts its expression domain in the Drosophila wing
(2007)The stable subdivision of Drosophila limbs into anterior and posterior compartments is a consequence of asymmetrical signalling by Hedgehog (Hh), from the posterior to anterior cells. The activity of the homeodomain protein ...

Human papillomavirus association with head and neck cancers: Understanding virus biology and using it in the development of cancer diagnostics
(2008)The link between human papillomaviruses (HPVs) and human cervical cancers has long been established. However, HPVs are now being detected in another type of cancer not previously associated with this virus, head and neck ...

Article
Human papillomavirus type 16 E6 and E7 oncoproteins act synergistically to cause head and neck cancer in mice
(2010)High-risk human papillomaviruses (HPVs) contribute to cervical and other anogenital cancers, and they are also linked etiologically to a subset of head and neck squamous cell carcinomas (HNSCC). We previously established ...

Article
The interplay between DSL proteins and ubiquitin ligases in Notch signaling
(2005)Lateral inhibition is a pattern refining process that generates single neural precursors from a field of equipotent cells and is mediated via Notch signaling. Of the two Notch ligands Delta and Serrate, only the former was ...

Investigation of substituent effect of 1-(3,3-diphenylpropyl)-piperidinyl phenylacetamides on CCR5 binding affinity using QSAR and virtual screening techniques
(2006)A linear quantitative-structure activity relationship model is developed in this work using Multiple Linear Regression Analysis as applied to a series of 51 1-(3,3-diphenylpropyl)-piperidinyl phenylacetamides derivatives ...

Article
Involvement of skeletal muscle gene regulatory network in susceptibility to wound infection following trauma
(2007)Despite recent advances in our understanding the pathophysiology of trauma, the basis of the predisposition of trauma patients to infection remains unclear. A Drosophila melanogaster/Pseudomonas aeruginosa injury and ...

Article
Nitric oxide activation and reduction by heme-copper oxidoreductases and nitric oxide reductase
(2008)The understanding of the dynamics and conformational control involved in the interplay between structure and function of nitric oxide reductase (Nor) and heme-copper oxidoreductases in their function to convert nitric oxide ...

Article
The nucleotide-binding proteins Nubp1 and Nubp2 are negative regulators of ciliogenesis
(2014)Nucleotide-binding proteins Nubp1 and Nubp2 are MRP/MinD-type P-loop NTPases with sequence similarity to bacterial division site-determining proteins and are conserved, essential proteins throughout the Eukaryotes. They ...

Article
A p53-mediated DNA damage response limits reprogramming to ensure iPS cell genomic integrity
(2009)The reprogramming of differentiated cells to pluripotent cells (induced pluripotent stem (iPS) cells) is known to be an inefficient process. We recently reported that cells with short telomeres cannot be reprogrammed to ...

The Polycomb Group Protein SUZ12 regulates histone H3 lysine 9 methylation and HP1α distribution
(2007)Regulation of histone methylation is critical for proper gene expression and chromosome function. Suppressor of Zeste 12 (SUZ12) is a requisite member of the EED/EZH2 histone methyltransferase complexes, and is required ...

The protein effect in the structure of two ferryl-oxo intermediates at the same oxidation level in the heme copper binuclear center of cytochrome c oxidase
(2013)Identification of the intermediates and determination of their structures in the reduction of dioxygen to water by cytochrome c oxidase (CcO) are particularly important to understanding both O2 activation and proton pumping ...

Proton binding to proteins: A free-energy component analysis using a dielectric continuum model
(2005)Proton binding plays a critical role in protein structure and function. We report pKa calculations for three aspartates in two proteins, using a linear response approach, as well as a "standard" Poisson-Boltzmann approach. ...

The role of the cross-link His-Tyr in the functional properties of the binuclear center in cytochrome c oxidase
(2002)Resonance Raman and Fourier transform infrared spectroscopies have been used to study the aa3-type cytochrome c oxidase and the Y280H mutant from Paracoccus denitrificans. The stability of the binuclear center in the absence ...
