The Ca2+-dependent Binding of Calmodulin to an N-terminal Motif of the Heterotrimeric G Protein beta Subunit [PDF]
, 1997 Ca2+ ion concentration changes are critical events in signal transduction. The Ca2+-dependent interactions of calmodulin (CaM) with its target proteins play an essential role in a variety of cellular functions.

Overlapping roles for PARP1 and PARP2 in the recruitment of endogenous XRCC1 and PNKP into oxidized chromatin [PDF]
, 2016 A critical step of DNA single-strand break repair is the rapid recruitment of the scaffold protein XRCC1 that interacts with, stabilizes and stimulates multiple enzymatic components of the repair process. XRCC1 recruitment is promoted by PARP1, an enzyme

Biological Reviews, EarlyView.ABSTRACT The complexity of breast cancer (BC) lung metastasis lies in the capacity of tumour cells to interact efficiently with distant organs to promote colonisation, a process that involves the sophisticated coordination of inherent cellular plasticity and the remodelling of the distant microenvironment.

ADPriboDB: The database of ADP-ribosylated proteins [PDF]
Nucleic Acids Research, 2016 ABSTRACT ADP-ribosylation refers to the addition of one or more ADP-ribose units onto proteins post-translationally. This protein modification is often added by ADP-ribosyltransferases, commonly known as PARPs, but it can also be added by other enzymes, including sirtuins or bacterial toxins. While past literature has

Nutrition-Based Modulation of Poly-ADP-Ribosylation and its possible role in Alzheimer’s disease [PDF]
, 2015 Alzheimer’s Disease (AD) is the most common neurodegenerative disease and the main reason of dementia in the elderly. On the pathological point of view, it is characterized by extracellular aggregates of amyloid peptides and intracellular deposits of tau

The human NAD metabolome: Functions, metabolism and compartmentalization [PDF]
, 2015 The metabolism of NAD has emerged as a key regulator of cellular and organismal homeostasis. Being a major component of both bioenergetic and signaling pathways, the molecule is ideally suited to regulate metabolism and major cellular events.

Interdisciplinary Medicine, EarlyView.This review illustrates how scientists engineer exosomes by hijacking the cell's own cargo‐sorting machinery. These strategies efficiently load therapeutic molecules into natural vesicles, creating powerful next‐generation drug delivery systems (Created with BioGDP.com).

A toxin hunter in the microworld of bacteria: a project on novel inhibitors against bacterial AB5 toxins [PDF]
, 2016 [要旨] 病原性細菌が産生する蛋白性のAB5型トキシンは1個のAサブユニットと5個のBサブユニットから構成される外毒素である。両サブユニットはそれぞれ特徴的な役割を持ち，互いに巧妙に機能分担をして一つのトキシンを形成している。Aサブユニットは主に毒性に直接関与する特異的な酵素活性を有する。一方，Bサブユニットは標的細胞のレセプターに対する結合能を有し，AB5型トキシンを標的細胞に吸着させる。ここでは毒性が全く異なるAB5型トキシンとして，コレラ菌が産生するコレラトキシン（CT ...

Ion Activation Methods for Top‐Down Proteomics
Mass Spectrometry Reviews, EarlyView.ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)
