Article
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 ...

Activation of endogenous FAK via expression of its amino terminal domain in xenopus embryos
(2012)Background: The Focal Adhesion Kinase is a well studied tyrosine kinase involved in a wide number of cellular processes including cell adhesion and migration. It has also been shown to play important roles during embryonic ...

Calpain2 protease: A new member of the Wnt/Ca2+ pathway modulating convergent extension movements in Xenopus
(2013)Calpains are a family of calcium-dependent intracellular cysteine proteases that regulate several physiological processes by limited cleavage of different substrates. The role of Calpain2 in embryogenesis is not clear with ...

A dominant-negative provides new insights into FAK regulation and function in early embryonic morphogenesis
(2013)FAK is a non-receptor tyrosine kinase involved in a wide variety of biological processes and crucial for embryonic development. In this manuscript, we report the generation of a new FAK dominant negative (FF), composed of ...

Article
FAK transduces extracellular forces that orient the mitotic spindle and control tissue morphogenesis
(2014)Spindle orientation is critical for proper morphogenesis of organs and tissues as well as for the maintenance of tissue morphology. Although significant progress has been made in understanding the mechanisms linking the ...

Article
High-resolution whole-mount in situ hybridization using quantum dot nanocrystals
(2012)The photostability and narrow emission spectra of nanometer-scale semiconductor crystallites (QDs) make them desirable candidates for whole-mount fluorescent in situ hybridization to detect mRNA transcripts in morphologically ...

Article
Imaging morphogenesis, in Xenopus with Quantum Dot nanocrystals
(2009)Mesoderm migration is a well studied morphogenetic movement that takes place during Xenopus gastrulation. The study of mesoderm migration and other morphogenetic movements has been primarily based on in vitro assays due ...

Article
In vivo imaging of quantum dots encapsulated in phospholipid micelles
(2002)Fluorescent semiconductor nanocrystals (quantum dots) have the potential to revolutionize biological imaging, but their use has been limited by difficulties in obtaining nanocrystals that are biocompatible. To address this ...

Article
Intein-mediated site-specific conjugation of Quantum Dots to proteins in vivo
(2009)We describe an intein based method to site-specifically conjugate Quantum Dots (QDs) to target proteins in vivo. This approach allows the covalent conjugation of any nanostructure and/or nanodevice to any protein and thus ...

Article
Making the Connection: Ciliary Adhesion Complexes Anchor Basal Bodies to the Actin Cytoskeleton
(2014)Cilia have been associated with diverse developmental and physiological processes, and defects in cilia underlie a number of genetic conditions. Several lines of evidence support a critical role of the actin cytoskeleton ...

Article
Samba, a Xenopus hnRNP expressed in neural and neural crest tissues
(2009)RNA binding proteins regulate gene expression at the posttranscriptional level and play important roles in embryonic development. Here, we report the cloning and expression of Samba, a Xenopus hnRNP that is maternally ...

Book Chapter
Single and multiplexed fluorescent in situ hybridization using quantum dots nanocrystals in Xenopus
(Springer New York, 2015)The photostability and narrow emission spectra of quantum dots (QDs) make them ideal candidates for whole-mount fluorescent in situ hybridization. Here we describe a method for non-amplified, single and multiplexed whole-mount ...

Article
Split-Inteins for Simultaneous, site-specific conjugation of Quantum Dots to multiple protein targets In vivo
(2011)Background: Proteins labelled with Quantum Dots (QDs) can be imaged over long periods of time with ultrahigh spatial and temporal resolution, yielding important information on the spatiotemporal dynamics of proteins within ...

Article
Xenopus laevis nucleotide binding protein 1 (xNubp1) is important for convergent extension movements and controls ciliogenesis via regulation of the actin cytoskeleton
(2013)Nucleotide binding protein 1 (Nubp1) is a highly conserved phosphate loop (P-loop) ATPase involved in diverse processes including iron-sulfur protein assembly, centrosome duplication and lung development. Here, we report ...
