Yeast Miro GTPase, Gem1p, regulates mitochondrial morphology via a novel pathway
Cell signaling events elicit changes in mitochondrial shape and activity. However, few mitochondrial proteins that interact with signaling pathways have been identified. Candidates include the conserved mitochondrial Rho (Miro) family of proteins, which contain two GTPase domains flanking a pair of calcium-binding EF-hand motifs. We show that Gem1p (yeast Miro; encoded by YAL048C) is a tail-anc...
متن کاملSystematic Structure-Function Analysis of the Small GTPase Arf1 in Yeast □D
Members of the ADP-ribosylation factor (Arf) family of small GTPases are implicated in vesicle traffic in the secretory pathway, although their precise function remains unclear. We generated a series of 23 clustered charge-to-alanine mutations in the Arf1 protein of Saccharomyces cerevisiae to determine the portions of this protein important for its function in cells. These mutants display a nu...

متن کاملComputational Analysis of Rho GTPase Cycling
The Rho family of GTPases control actin organization during diverse cellular responses (migration, cytokinesis and endocytosis). Although the primary members of this family (RhoA, Rac and Cdc42) have different downstream effects on actin remodeling, the basic mechanism involves targeting to the plasma membrane and activation by GTP binding. Our hypothesis is that the details of GTPase cycling b...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
