Protein Inference and Protein Quantification: Two Sides of the Same Coin [PDF]

open access: yesarXiv, 2012
Motivation: In mass spectrometry-based shotgun proteomics, protein quantification and protein identification are two major computational problems. To quantify the protein abundance, a list of proteins must be firstly inferred from the sample. Then the relative or absolute protein abundance is estimated with quantification methods, such as spectral ...

Measuring position sense

open access: yesExperimental Physiology, EarlyView.
Abstract Position sense is arguably more important than any of the other proprioceptive senses, because it provides us with information about the position of our body and limbs in relationship to one another and to our surroundings; it has been considered to contribute to our self‐awareness.

Monocytic cells become less compressible but more deformable upon activation.

open access: yesPLoS ONE, 2014
AimsMonocytes play a significant role in the development of atherosclerosis. During the process of inflammation, circulating monocytes become activated in the blood stream.

Is the intrinsic disorder of proteins the cause of the scale-free architecture of protein-protein interaction networks? [PDF]

open access: yesarXiv, 2006
In protein-protein interaction networks certain topological properties appear to be recurrent: networks maps are considered scale-free. It is possible that this topology is reflected in the protein structure. In this paper we investigate the role of protein disorder in the network topology.

Dual role for pannexin 1 at synapses: regulating functional and morphological plasticity

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Pannexin 1 (PANX1) regulation of dendritic spines. The postnatal decrease in PANX1 expression could release key spine cytoskeleton‐regulating proteins enabling spine stabilization. Does the physiological decrease in neuronal PANX1 levels across brain development underlie dendritic spine maturation?

Refining the Protein-Protein Interactome using Gene Expression Data [PDF]

open access: yesarXiv, 2010
Proteins interact with other proteins within biological pathways, forming connected subgraphs in the protein-protein interactome (PPI). Proteins are often involved in multiple biological pathways which complicates interpretation of interactions between proteins.

The RhoA guanine exchange factor ABR: a glucose‐sensitive mediator of actin reorganization in feto‐placental arterial endothelial cells altered by gestational diabetes mellitus

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of proposed relationship between hyperglycaemia, gestational diabetes mellitus (GDM), active BCR‐related (ABR), RhoA and actin organization of feto‐placental arterial endothelial cells (fpEC). Hyperglycaemia upregulates ABR, which in turn increases RhoA activation.

Head-neck domain of Arabidopsis myosin XI, MYA2, fused with GFP produces F-actin patterns that coincide with fast organelle streaming in different plant cells

open access: yesBMC Plant Biology, 2008
Background The cytoskeletal mechanisms that underlie organelle transport in plants are intimately linked to acto-myosin function. This function is mediated by the attachment of myosin heads to F-actin and the binding of cargo to the tails.

Protein token: a dynamic unit in protein interactions [PDF]

open access: yesarXiv, 2018
In this study, we introduced a new unit, named "protein token", as a dynamic protein structural unit for protein-protein interactions. Unlike the conventional structural units, protein token is not based on the sequential or spatial arrangement of residues, but comprises remote residues involved in cooperative conformational changes during protein ...

A role for synapsin tetramerization in synaptic vesicle clustering

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Model depicting how synapsin oligomers could serve both as a long‐range linker that interconnects synaptic vesicles to form a reserve pool of vesicles and as a spacer that circumvents short‐range electrostatic repulsion between the vesicles.
