The KCTD Family of Proteins: Structure, Function, Disease Relevance Zhepeng Liu1†, Yaqian Xiang2† and Guihong Sun1*
Liu et al. Cell & Bioscience 2013, 3:45 http://www.cellandbioscience.com/content/3/1/45 Cell & Bioscience REVIEW Open Access The KCTD family of proteins: structure, function, disease relevance Zhepeng Liu1†, Yaqian Xiang2† and Guihong Sun1* Abstract The family of potassium channel tetramerizationdomain (KCTD) proteins consists of 26 members with mostly unknown functions. The name of the protein family is due to the sequence similarity between the conserved N-terminal region of KCTD proteins and the tetramerization domain in some voltage-gated potassium channels. Dozens of publications suggest that KCTD proteins have roles in various biological processes and diseases. In this review, we summarize the character of Bric-a-brack,Tram-track, Broad complex(BTB) of KCTD proteins, their roles in the ubiquitination pathway, and the roles of KCTD mutants in diseases. Furthermore, we review potential downstream signaling pathways and discuss future studies that should be performed.

Prof. Tanja Slotte Stockholm University Department of Ecology, Environment and Plant Sciences Prof. Elias Arnér Karolinska Institutet Department of Medical Biochemistry and Biophysics ABSTRACT The medium-chain dehydrogenase/reductase (MDR) superfamily is a protein family with more than 170,000 members across all phylogenetic branches. In humans there are 18 repre- sentatives. The entire MDR superfamily contains many protein families such as alcohol dehy- drogenase, which in mammals is in turn divided into six classes, class I–VI (ADH1–6). Most MDRs have enzymatical functions, catalysing the conversion of alcohols to aldehyde/ketones and vice versa, but the function of some members is still unknown. In the first project, a methodology for identifying and automating the classification of mammalian ADHs was developed using BLAST for identification and class-specific hidden Markov models were generated for identification. -
Bioinformatic Protein Family Characterisation
Linköping studies in science and technology Dissertation No. 1343 Bioinformatic protein family characterisation Joel Hedlund Department of Physics, Chemistry and Biology Linköping, 2010 1 The front cover shows a tree diagram of the relations between proteins in the MDR superfamily (papers III–IV), excluding non-eukaryotic sequences as well as four fifths of the remainder for clarity. In total, 518 out of the 16667 known members are shown, and 1.5 cm in the dendrogram represents 10 % sequence differences. The bottom bar diagram shows conservation in these sequences using the CScore algorithm from the MSAView program (papers II and V), with infrequent insertions omitted for brevity. This example illustrates the size and complexity of the MDR superfamily, and it also serves as an illuminating example of the intricacies of the field of bioinformatics as a whole, where, after scaling down and removing layer after layer of complexity, there is still always ample size and complexity left to go around. The back cover shows a schematic view of the three-dimensional structure of human class III alcohol dehydrogenase, indicating the positions of the zinc ion and NAD cofactors, as well as the Rossmann fold cofactor binding domain (red) and the GroES-like folding core of the catalytic domain (green). This thesis was typeset using LYX. Inkscape was used for figure layout. During the course of research underlying this thesis, Joel Hedlund was enrolled in Forum Scientium, a multidisciplinary doctoral programme at Linköping University, Sweden.

Genomic Rearrangements of the 7Q11-21 Region
GENOMIC REARRANGEMENTS IN HUMAN AND MOUSE AND THEIR CONTRIBUTION TO THE WILLIAMS-BEUREN SYNDROME PHENOTYPE. by Edwin James Young A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy, Institute of Medical Science University of Toronto © Copyright by Edwin James Young (2010) Genomic rearrangements in human and mouse and their contribution to the Williams- Beuren Syndrome phenotype. Doctor of Philosophy (2010) Edwin James Young Institute of Medical Science University of Toronto Abstract: Genomic rearrangements, particularly deletions and duplications, are known to cause many genetic disorders. The chromosome 7q11.23 region in humans is prone to recurrent chromosomal rearrangement, due to the presence of low copy repeats that promote non-allelic homologous recombination. The most well characterized rearrangement of 7q11.23 is a hemizygous 1.5 million base pair (Mb) deletion spanning more than 25 genes. This deletion causes Williams-Beuren Syndrome (WBS; OMIM 194050), a multisystem developmental disorder with distinctive physical and behavioural features. Other rearrangements of the region lead to phenotypes distinct from that of WBS. Here we describe the first individual identified with duplication of the same 1.5 Mb region, resulting in severe impairment of expressive language, in striking contrast to people with WBS who have relatively well preserved language skills. We also describe the identification of a new gene for a severe form of childhood epilepsy through the analysis of individuals with deletions on ii chromosome 7 that extend beyond the boundaries typical for WBS. This gene, MAGI2, is part of the large protein scaffold at the post-synaptic membrane and provides a new avenue of research into both the molecular basis of infantile spasms and the development of effective therapies. -

Exposure to chemicals is suspected of playing a main role in the development of some adverse health effects in humans. Additionally, European regulatory authorities have recognized the risk associated with combined exposure to multiple chemicals. Testing all possible combinations of the tens of thousands environmental chemicals is impractical. This PhD project was launched to apply existing computational systems biology methods to toxicological research. In this thesis, I present in three projects three different approaches to using com- putational toxicology to aid classical toxicological investigations. In project I, we predicted human health effects of five pesticides using publicly available data. We obtained a grouping of the chemical according to their potential human health ef- fects that were in concordance with their effects in experimental animals. -
