Mechanisms of gradient sensing and chemotaxis are conserved in mammalian leukocytes and Dictyostelium amoebae. Both cells use G protein linked signaling pathways. PH domains specific for PtdIns(3,4)P2 and PtdIns(3,4,5)P3 bind to the membrane at the leading edge of the...

Regulation of Sterol Homeostasis Elevated serum cholesterol is a primary risk factor for heart disease. A negative feedback mechanism prevents excessive cellular cholesterol accumulation by regulating SREBP, a membrane-bound transcription factor that activates genes required for cholesterol biosynthesis and...

Background and Summary:Epithelial cells in a tissue live a crowded life connected to, and interacting with, other cell types, the extracellular matrix, and diverse signaling molecules. A fundamental question in biology is: how do the constituent cells of an...

The Fukunaga lab is broadly interested in RNA biology. More specifically, the Fukunaga lab investigates the mechanism and biology of post-transcriptional gene regulation controlled by small silencing RNAs and RNA-binding proteins. Our research projects will answer fundamental biological questions...

Animal cells secrete small vesicles (~50-250 nm diameter) that have the same topology as the cell. These vesicles, known as exosomes and microvesicles (EMVs), can be taken up by neighboring cells, completing a pathway of intercellular vesicle traffic. Our...

Neurotransmitter receptors mediate signal transduction at the postsynaptic membrane of synaptic connections between neurons in the nervous system. We have been studying the molecular mechanisms in the regulation of neurotransmitter receptor function. Recently we have focused on glutamate receptors,...

Eucaryotic RNA polymerase II is unique among RNA polymerases in containing an unusual repetitive domain at the C-terminus of the largest subunit. This C-terminal domain (CTD) is comprised of tandem repeats of the consensus sequence TyrSerProThrSerProSer. We are using...
