Abstract:
Lymphocyte antigen receptor engagement triggers activation of various signaling cascades, initiated by sequential activation of the Src and Syk families of protein tyrosine kinases, and leading to gene transcription. Although they lack both enzymatic and transcriptional activity, adaptor proteins are crucial for this process. The cytoplasmic adaptor protein 3BP2 contains a PH domain, proline–rich regions, and a SH2 domain, and interacts with Syk kinases, the LAT adaptor and the PLCg. 3BP2 plays a positive role in NK cytotoxicity, in basophilic degranulation, and activation of NFAT and AP-1 tra

Hydrodynamics is an effective theory that is extremely successful in describing a wide range of physical phenomena in liquids, gases and plasmas. However, our understanding of the structure of the theory, its microscopic origins and its behaviour at strong coupling is far from complete. To understand how an effective theory of dissipative hydrodynamics could emerge from a closed microscopic system, we analyse the structure of effective Schwinger-Keldysh Closed-Time-Path theories. We use this structure and the action principle for open systems to derive the energy-momentum balance equation for

Tauopathies are neurodegenerative diseases characterised by the pathological phosphorylation and accumulation of tau protein within the brain. Despite considerable efforts, the molecular pathways underlying tau pathogenesis have not yet been fully elucidated. This has been partially attributed to the limitations of traditionally used in vitro and in vivo models to recapitulate the complex molecular pathways involved in the pathogenesis of tau. The use of human induced pluripotent stem cell (hiPSC) technology has enabled the derivation of disease-relevant cell types from patients with tauopathy

Conventional computing faces a huge technical challenge as traditional transistors will soon reach their size limitations. This will halt progress in reaching faster processing speeds and to overcome this problem, require an entirely new approach. Quantum computing (QC) is a natural solution offering a route to miniaturisation by, for example, storing information in electron or nuclear spin states, whilst harnessing the power of quantum physics to perform certain calculations exponentially faster than its classical counterpart. However, QCs face many difficulties, such as, protecting the quantum-

The FA pathway is responsible for resolving DNA interstrand crosslinks (ICLs). While the exact mechanism is unknown, there are 21 confirmed proteins that belong to the pathway, and they can be all divided into three functional groups: the core complex, the FANCD2-FANCI complex and downstream effector proteins. It was demonstrated here that WRNIP1 depletion results in higher sensitivity to cross-linking agents (Mitomycin C (MMC) and UVA light after trioxalen (

Malaria is the most important parasitic disease in man and it kills approximately 2,000 people each day. Pregnant women are especially vulnerable to malaria with increased incidence and mortality rates. There are indications that pregnancy alters the pharmacokinetic properties of many antimalarial drugs. This is worrisome as lower drug exposures might result in lowered efficacy and lower drug exposures can also accelerate the development and spread of resistant parasites.

3BP2 has been previously described as the protein mutated in the osteoporotic disorder, Cherubism. The gain of function mutation that characterizes Cherubism is the result of an uncoupling of its interaction with Tankyrase 2, which has been reported to stimulate 3BP2 ubiquitination. Here we describe an attempt at identifying the E3 ligase responsible for mediating this ubiquitination using four candidate members from the Nedd4 family. Based on their respective abilities to bind and ubiquitinate 3BP2, as well as their sensitivity to the presence of Tankyrase 2 and to 3BP2 mutations (includin

Abstract:
3BP2 was originally identified through its interaction with the ABL kinase. Fusion of ABL with the BCR gene forms the BCR-ABL onco-protein, which is causative in Chronic Myeloid Leukemia (CML) and acute lymphoid leukemia (ALL). Due to the ability of 3BP2 to regulate ABL activity in osteoblasts, we hypothesize that 3BP2 modulates BCR-ABL signalling. Overexpression of 3BP2 in the CML-T1 cell line produced a marked decrease in global tyrosine phosphorylation. 3BP2 overexpression also resulted in a significant increase in CML-T1 cell growth, accompanied by altered ERK1/2, AKT, SYK, LYN, HCK, and C
