Mastoparan (MP), a cationic, amphiphilic tetradecapeptide, stimulates guanine nucleotide exchange by GTP-binding regulatory proteins (G proteins) in a manner similar to that of G protein-coupled receptors. 1) MP stimulated exchange by isolated G protein alpha subunits and alpha beta gamma

Constitutive membrane trafficking events are regulated by heterotrimeric G-proteins (G-proteins) in addition to their regulation by small GTP-binding proteins (smgs). Here, we used streptolysin O-permeabilized mouse pancreatic acini and compounds that interact with G-proteins, but not smgs, to examine whether

We have previously described that mastoparan, an amphiphilic tetradecapeptide that activates heterotrimeric G-proteins, inhibits Ca(2+)-induced MgATP-dependent secretion from streptolysin-O-permeabilized chromaffin cells [Vitale, Mukai, Rouot, Thiersé, Aunis and Bader (1993) J. Biol. Chem. 268, 14715-14723]. Our observations suggest the involvement of

Aberrant Notch and Wnt signaling are known drivers of cholangiocarcinoma (CCA), but the underlying factors that initiate and maintain these pathways are not known. Here, we show that the proline-rich homeodomain protein/hematopoietically expressed homeobox (PRH/HHEX) transcription factor forms a positive
