Interaction of Galectin-1 with human NK cell receptors
 de Sousa Santos Abreu, Celeste ; Vaněk, Ondřej (advisor) ; Pavlíček, Jiří (referee)
Natural killer (NK) cells are a subpopulation of effector lymphocytes with cytotoxic activity and cytokine-producing functions considered as an integral part of the innate immune response. Functions of NK cells include tumour elimination, engagement and regulation of antiviral immune responses and regulation of immune cells by production and secretion of chemokines and cytokines. CD69 is a C-type lectin-like transmembrane receptor expressed in NK cells. CD69 is an activating receptor and acts also as a very early marker of lymphocyte activation. Putative protein ligands have been described for CD69 in the last years: Galectin-1, S1P1, S100A8/S100A9 and Myl9/12. Galectin-1 is a prototypical lectin characterized by the presence of a common lectin structural fold and a carbohydrate recognition domain involved in carbohydrate binding. Galectin-1 was identified as a binding partner for CD69 based on biological and functional studies, but structural details about the complex are still missing. This thesis describes the successful establishment of an expression protocol for a tag-less cysteine-less mutant of galectin-1 and the study of the interaction between galectin-1 and NK cell receptors. The interaction was studied using microscale thermophoresis and confirmed as dependent on the presence of a...

Analysis of Histone Deacetylase 6/Kinesin Interactions
 Nedvědová, Jana ; Bařinka, Cyril (advisor) ; Pavlíček, Jiří (referee)
Intracellular transport is provided by two major types of molecular motors kinesins and cytoplasmic dynein. Kinesin-1 is a molecular motor that transports molecules and organelles along microtubule tracks anterogradely. Specific protein-protein interactions are required to activate kinesin-1 as the free kinesin exist in an autoinhibited state. The activation of kinesin-1 induces its conformational change, enables microtubule binding and ATP hydrolysis necessary for the directional cargo transport. HDAC6 is a multifunctional protein composed of several domains. It plays an important role in many microtubule dependent processes as HDAC6 is a major tubulin deacetylase. It has been shown that HDAC6 manipulation (inhibition/genetic ablation) affects transport along microtubules but the exact mechanisms are unknown. The effect can be caused either by deacetylation microtubules or direct interaction with molecular motors. This thesis is focused on characterization of interactions between kinesin-1 and HDAC6 that have not been described so far. To this end, we expressed and purified various constructs of kinesin-1 and HDAC6 and tested their interactions by microscale thermophoresis (MST) and hydrogen deuterium exchange (HDX) to determine affinity and interaction sites, respectively. MST data revealed that...
