It is a phenomenon that Arabidopsis and human genomes encode only a few members (six and two, respectively) of the MATH-BTB protein family, but in some plant and animal organisms, the same protein family has expanded more than 10-fold. The first functionally characterized MATH-BTB protein is Mel26 from Caenorhabditis elegans which is a key regulator required for the first symmetric zygote division. Three different plant MATH-BTB genes, from Zea mays, Triticum aestivum and Arabidopsis thaliana were selected due to their exclusive\/strong expression during plant reproduction and functionally characterized in our work. A gametophyte\/zygote specific ZmMAB1 gene from maize is expressed in both the female and male germline and its silencing leads to defects in spindle organization and chromosome segregation during gametophyte development. The zygotic induced gene TaMAB2 encodes a protein that asymmetrically co-localises with microtubules around the nuclear envelope, which suggests its role in organizing the assembly and proper position of microtubular spindles during asymmetric cell divisions of the zygote. Moreover, the zygote deposited TaMAB2 is always inherited to the large basal cell after the first asymmetric zygotic division. The asymmetrically inheritance indicates that the protein might be involved not only in the establishment of asymmetry but also in the cell specification in the two-celled embryo. ZmMAB1 and TaMAB2 as well as other yeast, animal, and plant BTB-domain containing proteins interact with Cullin 3-based E3 ligases and are involved in ubiquitin-dependent degradation pathway. In addition to Cullin 3-related functions, Arabidopsis MATH -BTB protein AtBPM1, localizes predominantly in the nucleolus of plant cells indicating a Cullin3 independent function. We identified, by mass spectrometry and other protein interaction analysis, that AtBPM1 interacts with proteins involved in RNA-directed DNA methylation which represent a novel, yet undiscovered function of MATH-BTB protein in regulation of DNA methylation.<\/p>","protected":false},"excerpt":{"rendered":"<p>Lecturer: DUNJA LELJAK-LEVANI\u0106, Ph.D.Department of Molecular Biology, Faculty of Science, Zagreb Date and time Thursday, September 26, 2016.
