  2. 11. Structure and organization of genes for the predominant seminal plasma proteins semenogelin I, semenogelin II and beta-microseminoprotein

    Author : Magnus Ulvsbäck; Malmö Klinisk kemi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical chemistry; transglutaminase substrate; semen coagulation; prostate; seminal vesicles; seminal plasma; rhesus monkey; human; evolution; nucleic acid sequence; cDNA; gene; semenogelin; b-microseminoprotein; Klinisk kemi; Proteins; enzymology; Proteiner; enzymologi;

    Abstract : In man, the predominant proteins in the seminal plasma include semenogelin I, semenogelin II and b-microseminoprotein (MSP). Semenogelin I and II are both synthesized in the seminal vesicles and are the backbone of the gel formed upon semen coagulation. MSP is synthesized in the prostate, but its role has not yet been defined. READ MORE

  4. 12. Protein Folding, Binding and Evolution : PDZ domains and paralemmins as model systems

    Author : Greta Hultqvist; Per Jemth; Ruth Nussinov; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein folding; evolution; binding; allostery; Paralemmin; PDZ domain;

    Abstract : Proteins present at the synapse need to be multitasking in order to perform all vital functions in this limited space. In this thesis I have analyzed the function and evolution of such proteins, focusing on the PDZ domain and the paralemmin family. The PDZ domains bind to a wide variety of interaction partners.

  5. 13. Evolution of the Neuropeptide Y System in Vertebrates with Focus on Fishes

    Author : Tomas Larsson; Dan Larhammar; Svante Winberg; Kenneth H. Wolfe; Uppsala universitet; []
    Keywords : Molecular biology; neuropeptide Y; GPCR; evolution; gene duplication; vertebrates; ray-finned fishes; Molekylärbiologi;

    Abstract : Gene families in vertebrates often contain more dulicates (paralogs) than in invertebrates. This has been attributed to genome duplications, i.e., tetraploidizations. READ MORE

  6. 14. Evolution of eyes: Pax, gene duplications & morphology

    Author : Karin Nordström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; animal morphology; Djurs anatomi och morfologi; Animal anatomy; tetraploidization; planula; phototransduction; pax; paired domain; mutagenesis; cnidaria; eye evolution;

    Abstract : During the course of evolution animal complexity and diversity is generated. The last couple of years it has become increasingly clear that morphologically diverse animals share a great deal of their genomic contents, and it must be the expression of regulatory genes in new setting, rather than the generation of new genes, that are fundamental for the generation of diversity.

  7. 15. Evolution of the Neuropeptide Y and Opioid Systems and their Genomic Regions

    Author : Görel Sundström; Dan Larhammar; Manfred Schartl; Uppsala universitet; []
    Keywords : neuropeptide Y; opioid; evolution; genome duplication; gene duplication; Hox; SCN; IGFBP; MEDICINE; MEDICIN;

    Abstract : Two whole genome duplications (2R) occurred early in vertebrate evolution. By using combined information from phylogenetic analyses and chromosomal location of genes, this thesis delineates the evolutionary history of two receptor-ligand systems that expanded by these large scale events.
