Recombinant preparation of isotopically labeled receptor rNKR-P1A for NMR studies
Čonka, Martin ; Bezouška, Karel (advisor) ; Novák, Petr (referee)
anglicky NK cells belong to the population of cells which are able to cytotoxic kill certain tumor and cells infected by viruses. This bachelor thesis focuses on the rat's NK cell receptor, especially rNKR-P1A. This protein belongs to the activating receptors and is able to activate the cytotoxic function of NK cells. Physiological ligand and three-dimensional structure of this protein has not been resolved yet. The aim of this work was optimalization of production rNKR-P1A in minimal medium and thereafter producing isotope-labeled proteins. Isotope- labeled proteins could contribute to solving the three-dimensional structure of this rat receptor by using NMR methods.

Expression of the recombinant extracellular parts of leukocyte receptors AICL a NKR-P1CBALB
Čonka, Martin ; Novák, Petr (advisor) ; Cebecauer, Marek (referee)
v anglickém jazyce NK cells represent a population of lymphocytes which are able to kill certain tumor cells or virally infected cells. The subject of the diploma thesis is a mouse NK cell receptor mNKR- P1CBALB and a human leukocyte receptor hAICL. The mNKR-P1CBALB belongs to the activating receptors and is able to activate the cytotoxic functions of NK cells. The hAICL receptor is a ligand to the NKp80 which is an activating receptor of NK cells. Interaction between these two proteins leads to the activation of effector functions of NK cells as well. The aim of this work was the preparation of the recombinant extracellular parts of receptors mNKR-P1CBALB and hAICL, the optimalization of their in vitro refolding and the characterization of proteins using mass spectrometry. The proteins samples will be used for further structural study of the extracellular parts of these leukocytes receptors.
