PDE6δ-mediated sorting of INPP5E into the cilium is determined by cargo-carrier affinity [PDF]
The phosphodiesterase 6 delta subunit (PDE6δ) shuttles several farnesylated cargos between membranes. The cargo sorting mechanism between cilia and other compartments is not understood.

IQGAP Family Members in Yeast, Dictyostelium, and Mammalian Cells
IQGAPs are a family of scaffolding proteins with multiple domains, named for the IQ motifs and GTPase activating protein (GAP) related domains. Despite their GAP homology, IQGAP proteins act as effectors for GTP-bound GTPases of the Ras superfamily and ...

The GTP- and Phospholipid-Binding Protein TTD14 Regulates Trafficking of the TRPL Ion Channel in Drosophila Photoreceptor Cells. [PDF]
Recycling of signaling proteins is a common phenomenon in diverse signaling pathways. In photoreceptors of Drosophila, light absorption by rhodopsin triggers a phospholipase Cβ-mediated opening of the ion channels transient receptor potential (TRP) and ...

Mutations in human dynamin block an intermediate stage in coated vesicle formation [PDF]
The role of human dynamin in receptor-mediated endocytosis was investigated by transient expression of GTP-binding domain mutants in mammalian cells. Using assays which detect intermediates in coated vesicle formation, the dynamin mutants were found to ...

Molecules and mechanisms that regulate multipolar migration in the intermediate zone
Most neurons migrate with an elongated, bipolar morphology, extending a long leading process that explores the environment. However, when immature projection neurons enter the intermediate zone of the neocortex they become multipolar.

Divergent Mechanisms Activating RAS and Small GTPases Through Post-translational Modification
RAS is a founding member of the RAS superfamily of GTPases. These small 21 kDa proteins function as molecular switches to initialize signaling cascades involved in various cellular processes, including gene expression, cell growth, and differentiation ...
