Hetero-tetrameric soluble N-ethylmaleimide-sensitive factor attachment protein receptors(SNAREs)complexes are critical for vesicle-target membrane fusion within the endomembrane system of eukaryotic cells. SNARE assembly involves four different SNARE motifs, Qa, Qb, Qc, and R, provided by three or four SNARE proteins. YKT6 is an atypical R-SNARE that lacks a transmembrane domain and is involved in multiple vesicle-target membrane fusions. Although YKT6 is evolutionarily conserved and essential, its function and regulation in different phyla seem distinct. Arabidopsis YKT61, the yeast and metazoan YKT6homologue, is essential for gametophytic development, plays a critical role in sporophytic cells, and mediates multiple vesicle-target membrane fusion. However, its molecular regulation is unclear. We report here that YKT61 is S-acylated. Abolishing its S-acylation by a C195S mutation dissociates YKT61 from endomembrane structures and causes its functional loss. Although interacting with various SNARE proteins, YKT61 functions not as a canonical R-SNARE but coordinates with other R-SNAREs to participate in the formation of SNARE complexes. Phylum-specific molecular regulation of YKT6 may be evolved to allow more efficient SNARE assembly in different eukaryotic cells.

以波浪形自由曲面网壳为研究对象,介绍了其几何特征,归纳了相应的几何特征参数.利用Grasshopper平台实现了波浪形自由曲面基于NURBS理论的参数化构形和基于等参线分割的参数化网格生成.该方法可对波浪形自由曲面壳方便地实现凯威特型、肋环形、肋环斜杆型、斜放四边形网格等网格形式的参数化建模和网格尺寸调整.在此基础上,进行了球面网壳和不同程度波浪特征的波浪形自由曲面网壳的稳定性对比分析.结果表明,在球壳基础上引入波浪特征会改变结构刚度的分布,且随着波浪特征值的加大,结构极限承载力和整体刚度呈现先减小后增大的趋势.

In this paper, we investigate Galton-Watson branching processes in random environments. In the case where the environmental process is a Markov chain which is positive recurrent or has a transition matrix Q (θ,α) such that sup_θ Q (θ,α)> 0 for some α, we prove that the model has the asymptotic behavior being similar to that of Galton-Watson branching processes. In other case where the environments are non-stationary independent, the sufficient conditions are obtained for certain extinction and uncertain extinction for the model.
