Membrane contact site
- RDGBα localization and function at membrane contact sites is regulated by FFAT–VAP interactions
Summary: FFA–VAP interactions regulate lipid transfer activity in Drosophila photoreceptors during PLC signalling.
- Junctate boosts phagocytosis by recruiting endoplasmic reticulum Ca2+ stores near phagosomes
Highlighted Article: The STIM1-interacting protein junctate generates Ca2+ hotspots that boost phagocytosis independently of STIM1 by promoting Ca2+ release from ER stores rather than by gating phagosomal Ca2+ channels.
