Book Description
This is the first book to assemble the leading researchers in the field of LRRK2 biology and neurology and provide a snapshot of the current state of knowledge, encompassing all major aspects of its function and dysfunction. The contributors are experts in cell biology and physiology, neurobiology, and medicinal chemistry, bringing a multidisciplinary perspective on the gene and its role in disease. The book covers the identification of LRRK2 as a major contributor to the pathogenesis of Parkinson's Disease. It also discusses the current state of the field after a decade of research, putative normal physiological roles of LRRK2, and the various pathways that have been identified in the search for the mechanism(s) of its induction of neurodegeneration.

Book Description
Mutations in Leucine-Rich Repeat Kinase 2 (LRRK2) are one of the most common causes of genetic Parkinson's disease (PD), with mutations thought to account for around 5% of all familial cases. LRRK2 is a large protein with a kinase and GTPase domain and multiple protein--protein interaction domains. Regulation of this protein is complex, with GTPase activity known to regulate kinase activity. Similarly, LRRK2 can autophosphorylate and is thought to form a dimer when active. Mutations in LRRK2 are numerous, with the most prevalent mutations occurring in the enzymatic core of this protein. This thesis describes work done to characterise the regulation and functioning of LRRK2, in order to further contribute towards understanding how mutations in this protein can lead to the pathogenesis of PD. Using BlueNative PAGE and glycerol gradient centrifugation, the quaternary structure of LRRK2 was assessed. In vitro kinase assays were used to characterise kinase activity of recombinant LRRK2 and a number of putative kinase substrates were also investigated. Identification of new kinase substrates was attempted and immunoprecipitation of LRRK2 to identify novel binding partners was also performed. Results of these experiments showed that familial mutations do not affect the ability of LRRK2 to form complexes. Instead, some mutations are affecting the enzymatic activity of LRRK2. Dephosphorylating LRRK2 showed that dimer formation is dependent on phosphorylation. Dephosphorylated forms of LRRK2 were more likely to be monomeric and displayed lower kinase activity than higher molecular weight forms. In vitro kinase assays to evaluate LRRK2 kinase substrates showed that [alpha]-synuclein is phosphorylated at low levels by G2019S but not wild-type LRRK2. Attempts to identify novel kinase substrates and binding partners of LRRK2 were unsuccessful, however evaluation of putative kinase substrates in vitro showed that DVL3 and TUBB5 may be good candidates for further investigation, as they were robustly phosphorylated by LRRK2. These results contribute towards our understanding of how LRRK2 functions and future studies based on these results may prove useful in aiding our understanding of how LRRK2 can cause PD pathogenesis.

Book Description
Connects fundamental knowledge of multivalent interactions with current practice and state-of-the-art applications Multivalency is a widespread phenomenon, with applications spanning supramolecular chemistry, materials chemistry, pharmaceutical chemistry and biochemistry. This advanced textbook provides students and junior scientists with an excellent introduction to the fundamentals of multivalent interactions, whilst expanding the knowledge of experienced researchers in the field. Multivalency: Concepts, Research & Applications is divided into three parts. Part one provides background knowledge on various aspects of multivalency and cooperativity and presents practical methods for their study. Fundamental aspects such as thermodynamics, kinetics and the principle of effective molarity are described, and characterisation methods, experimental methodologies and data treatment methods are also discussed. Parts two and three provide an overview of current systems in which multivalency plays an important role in chemistry and biology, with a focus on the design rules, underlying chemistry and the fundamental principles of multivalency. The systems covered range from chemical/materials-based ones such as dendrimers and sensors, to biological systems including cell recognition and protein binding. Examples and case studies from biochemistry/bioorganic chemistry as well as synthetic systems feature throughout the book. Introduces students and young scientists to the field of multivalent interactions and assists experienced researchers utilising the methodologies in their work Features examples and case studies from biochemistry/bioorganic chemistry, as well as synthetic systems throughout the book Edited by leading experts in the field with contributions from established scientists Multivalency: Concepts, Research & Applications is recommended for graduate students and junior scientists in supramolecular chemistry and related fields, looking for an introduction to multivalent interactions. It is also highly useful to experienced academics and scientists in industry working on research relating to multivalent and cooperative systems in supramolecular chemistry, organic chemistry, pharmaceutical chemistry, chemical biology, biochemistry, materials science and nanotechnology.
