Article Citation - WoS: 219Citation - Scopus: 242The Importance of Boron in Biological Systems(Urban und Fischer Verlag GmbH und Co. KG, 2018) Uluışık, İrem; Karakaya, Hüseyin Çağlar; Koç, AhmetBoron is an essential element for plants and probably essential for human and animal health. Boron has a broad range of physiological effects on biological systems at low concentrations, whereas it is toxic to at high concentrations. Eventhough there are many studies on boron's biological effects and toxicity, more information is needed to understand the mechanisms of its action. The aim of the current work is to review boron's function, transport and toxicity in different biological systems.Article Citation - WoS: 8Citation - Scopus: 10Functional Characterization of New Mutations in Wilson Disease Gene (atp7b) Using the Yeast Model(Urban und Fischer Verlag GmbH und Co. KG, 2015) Şimşek Papur, Özlenen; Terzioğlu, Orhan; Koç, AhmetThe Wilson disease gene, a copper transporting ATPase (Atp7b), is responsible for the sequestration of Cu into secretory vesicles, and this function is exhibited by the orthologous Ccc2p in the yeast. In this study, we aimed to characterize clinically relevant new mutations of human ATP7B (p.T788I, p.V1036I and p.R1038G-fsX83) in yeast lacking the CCC2 gene. Expression of human wild type ATP7B gene in ccc2δ mutant yeast restored the growth deficiency and copper transport activity; however, expression of the mutant forms did not restore the copper transport functions and only partially supported the cell growth. Our data support that p.T788I, p.V1036I and p.R1038G-fsX83 mutations cause functional deficiency in ATP7B functions and suggest that these residues are important for normal ATP7B function.
