A 3rd new article: the teams of Laura Lackner (Norhtwestern) and Tom Burgoyne (UCL) jointly review zones of contact between mitochondria and the plasma membrane across a wide variety of organisms, speculating on unknowns and discussing unanswered questions journals.sagepub.com/doi/full/10.11…

Another new article: Ida J. van der Klei and colleagues (Groningen) show the Pex23 family of ER proteins with dysferlin domains have unexpected roles in aspects of lipid droplet function that are suppressed by an artificial ER-mitochondrion tether. journals.sagepub.com/doi/full/10.11…

We have a new article from Emma Fenech, Maya Schuldiner & co. (Weizmann, Rehovot) on the yeast LAM family of sterol transfer proteins. They use proximity labeling to compare all 6 proteins, finding unique functions for paralogs and new functional links. journals.sagepub.com/doi/full/10.11…

Did you know we are the only journal dedicated to research on membrane contact sites? And yet the scope is wide - from lipidology to applications in human disease. Check it out: journals.sagepub.com/overview-metri…

Our latest article about proteostasis pathways shared between organelles is from @AKohler_Mito & @_VerenaKohler @umeauniversity. They address how proteostasis requires both major signalling processes (integrated stress response (ISR), UPR + more) and also direct physical contact.

🥳Excited to share that our latest article is now online! journals.sagepub.com/doi/full/10.11… In this review, @AKohler_Mito and I focussed on #Proteostasis mechanisms over #OrganellarBorders #MembraneContactSites #ProteinQualityControl #InterorganellarCommunication #Mitochondria #ER

The team of Mark Von Zastrow @UCSFPsychiatry show that one aspect of cAMP compartmentalization is through specific intracellular targeting of adenyl cyclases. "these results reveal a precise spatial landscape of the cAMP cascade" nature.com/articles/s4146…

Our most recent article is out: Johannes Frietag Thorsten Stehlik & Gert Bange (Marburg) describe a simple, powerful mechanism they recently uncovered for interaction between organelles: proteins with targeting sequences for both organelles are pulled both ways at the same time!!

Interested in bagpipes* and membrane contacts? Come to Edinburgh this September for the @BiochemSoc meeting on one of these! Organized by the amazing @timlevine1, @MariaBohnert, @edenlab_ucl, and Pat Hussey. bit.ly/Membrane24 *Mike promises he will not play bagpipes.

The Meyer lab @WeillCornell show ER-PM contacts are involved in cell migration. Contacts are static in relation to cell matrix, so as a cell moves contacts go to the back. They turn off EGFR signals via PTP1B, propelling cells forward. See paper for details on contact asymmetry.
New York Structural Biology Center@NYSBC_Science

Another fantastic example of a successful collaboration between NYSBC and NY. Tobias Meyer's group at @WeillCornell show the role that the ER plays in cell polarization and migration. Shout out to Bo Gang @WeillCornell and Jake Johnston @NYSBC_Science:nature.com/articles/s4158…

The team of @LacknerLabNU at Northwestern University have shown that 3 way mitochondria/plasma membrane/ER contacts in yeast need the tether Num1 to bind VAP. Their outputs include regulating PI4P at the PM and mitochondrial division. The team offer lots of ideas for future work.

The group of Natividad Ruiz @OhioState have further mapped the role of RBG proteins in bacterial lipid traffic An RBG protein too short to cross the periplasm functions only when a protein in the same operon augments the b-structure to complete the bridge pnas.org/doi/10.1073/pn…

New work from the Imperi group #Roma3 study phospholipid traffic in Pseudomonas. Four out of the seven AsmA homologs (tamB, yhdP, ydbH, PA4735) are redundantly essential (at least one is required). There is rescue by lower LPS delivery, showing balance between the 2 OM leaflets.

There's a new paper from the @Oidevall group (Uppsala) who show that insulin granules form contacts with the ER where OSBP is recruited (Ca2+ and pH- dependent) to exchange granule PI(4)P for ER cholesterol, hence allowing normal insulin secretion.
