Examination of the changes in the transcription start site selection in TCL1-driven chronic lymphocytic leukemia and their impact on mRNA translation revealed a marked elevation of intra-genic cryptic promoters, which are predicted to generate multiple N-terminally truncated or modified proteins.

Cutting-edge super-resolution microscopy methods reveal the architecture and dynamics of the sealing zone formed by human osteoclasts and composed of coordinated groups of podosomal cores encircled by adhesion complexes.

Using mass spectrometry to study protein composition of translating ribosomes under unstressed or stress conditions, aspartate aminotransferase 2 (Aat2) is identified as a metabolic enzyme with a moonlighting function in the yeast integrated stress-response pathway.

A novel, inexpensive, easy-to-use method to analyse traffic along the endosomal pathway in mammalian cells shows that there is coordination between Rab conversion and acidification, but almost none between Rab conversion and recycling.
The USP-50/USP8 protease removes the Rab5 GEF Rabex5 from endosomes while facilitating recruitment of the Rab7 GEF SAND-1/Mon1, promoting endosome maturation.

Cation chloride cotransporter CCC1 has a central function in plant cells and is the missing ion efflux component of the transport circuit necessary to regulate pH in the lumen of the trans-Golgi-network/early endosome, the major cargo hub in plant cells.

Postsynaptic MT1-MMP serves as a molecular switch to synaptogenesis by clearing the surrounding ECM environment that allows effective deposition of nerve-derived synaptogenic factors to induce postsynaptic differentiation at developing NMJs.

Translationally active polysomes from mammalian cells/tissues are successfully separated with rapidity, high efficiency and exceptional reproducibility by a SEC-based approach, an accessible alternative to the conventional sucrose density gradient analysis.

An endosomal component employs a novel PAM2-like motif to recruit a key RNA-binding protein, which explains how mRNAs and associated ribosomes are attached to endosomes during coupled transport.
