CD14 is a glycosylphosphatidylinositol (GPI)-anchored protein on the surfaces of monocytes and polymorphonuclear leukocytes (PMN) that binds and initiates cellular responses to bacterial LPS. PMN also contain an intracellular pool of CD14 that can be deployed rapidly to the cell surface in response to stimulation with a variety of agonists. ... More

O-GlcNAc transferase (OGT) modifies nuclear pore proteins and transcription factors. In Arabidopsis, the OGT homolog participates in the gibberellin signaling pathway. We and others have proposed that mammalian OGT is the terminal step in a glucose-sensitive signal transduction pathway that becomes disregulated in insulin resistance. To facilitate mutational analysis of ... More
