Phylogenetic profiling and cellular analyses of ARL16 reveal roles in traffic of IFT140 and INPP5E.

The ARF family of regulatory GTPases is ancient, with 16 members predicted to have been present in the last eukaryotic common ancestor. Our phylogenetic profiling of paralogues in diverse species identified four family members whose presence correlates with that of a cilium/flagellum: ARL3, ARL6, ARL13, and ARL16. No prior evidence links ARL16 to cilia or other cell functions, despite its presence throughout eukaryotes.

The ARF GAPs ELMOD1 and ELMOD3 act at the Golgi and cilia to regulate ciliogenesis and ciliary protein traffic.

ELMODs are a family of three mammalian paralogues that display GTPase-activating protein (GAP) activity toward a uniquely broad array of ADP-ribosylation factor (ARF) family GTPases that includes ARF-like (ARL) proteins. ELMODs are ubiquitously expressed in mammalian tissues, highly conserved across eukaryotes, and ancient in origin, being present in the last eukaryotic common ancestor. We described functions of ELMOD2 in immortalized mouse embryonic fibroblasts (MEFs) in the regulation of cell division, microtubules, ciliogenesis, and mitochondrial fusion.

Advancing bodies of evidence for population-based health promotion programs: randomized controlled trials and case studies.

This study provides a demonstration of how published intervention outcomes can be used to create benchmarks for wellness programs for comparison of a case study. Case study results can then be applied by decision makers to adopt and evaluate the relative effectiveness of wellness programs. This case study assessed outcomes from Transtheoretical Model (TTM) computer-tailored interventions (CTIs) on 6 behaviors over a 5-year period.

Structural studies of the Msx-1 homeodomain-DNA complex I.

Crystals of the Msx-1 homeodomain-DNA complex have been obtained by hanging-drop vapor diffusion at 293 K in 12% PEG 4000 and 0.1 M sodium acetate pH 4.6.
