Homotypic fusion and vacuole protein sorting (HOPS) is a tethering complex required for trafficking to the vacuole/lysosome in yeast. Specific interaction of HOPS with certain SNARE (soluble NSF attachment protein receptor) proteins ensures the fusion of appropriate vesicles. HOPS function is less well characterized in metazoans. We show that all six HOPS subunits (Vps11 [vacuolar protein sorti...

MLL is a common target for chromosomal translocations associated with acute leukemia resulting in its fusion with a large variety of nuclear or cytoplasmic proteins that may activate its oncogenic properties by distinct but poorly understood mechanisms. The MLL-AF6 fusion gene represents the most common leukemogenic fusion of mixed lineage leukemia (MLL) to a cytoplasmic partner protein. Here, ...

Dysferlin has recently been reported to participate in cell membrane repair in muscle and other cells through lysosome fusion. Given that lysosome fusion is a crucial mechanism that leads to membrane raft clustering, the present study attempted to determine whether dysferlin is involved in this process and its related signalling, and explores the mechanism underlying dysferlin-mediated lysosome...

To gain insights into the mechanisms by which soluble heat shock protein (hsp) fusions can elicit CD8 1 cytotoxic T lymphocytes (CTLs) against the fusion partner, mycobacterial ( Mycobacterium tuberculosis ) hsp70 was dissected to ascertain whether a particular hsp domain is necessary, and knockout mice were used to determine whether the fusion protein’s immunogenicity is dependent on CD4 1 T l...

the fusion of medical images is very useful for clinical application. generally, the pet image indicates the function of tissue and the mri image shows the anatomy of tissue. in this article we fused mri and pet images and the purpose is adding structural information from mri to pet image. the images decomposed with curvelet transform, and then two images fused with applying fusion rules. we us...

The identification of recurrent gene fusions in common epithelial cancers--for example, TMPRSS2/ERG in prostate cancer and EML4/ALK in nonsmall cell lung carcinomas--has raised the question of whether fusion genes are pathogenetically important also in ovarian carcinomas. The first recurrent fusion transcript in serous ovarian carcinomas was reported by Salzman et al. in 2011, who used deep pai...

Cell polarization involves specifying an area on the cell surface and organizing the cytoskeleton towards that landmark. The mechanisms by which external signals are translated into internal landmarks for polarization are poorly understood. The yeast Saccharomyces cerevisiae exhibits polarized growth during mating: the actin cytoskeleton of each cell polarizes towards its partner, presumably to...
