[HTML][HTML] cAMP regulates Ca2+-dependent exocytosis of lysosomes and lysosome-mediated cell invasion by trypanosomes

A Rodrıguez, I Martinez, A Chung, CH Berlot… - Journal of Biological …, 1999 - ASBMB
Ca 2+ -regulated exocytosis, previously believed to be restricted to specialized cells, was
recently recognized as a ubiquitous process. In mammalian fibroblasts and epithelial cells, …

Identification of effector-activating residues of Gsα

CH Berlot, HR Bourne - Cell, 1992 - cell.com
The heterotrimeric G proteins transduce extracellular signals by interacting with specific
intracellular effectors. We have used a scanning mutagenesis approach to identify amino acids …

Geranylgeranylation signals to the Hippo pathway for breast cancer cell proliferation and migration
