Western blot indicates ULK1 knockdown. Scale bars = 20 μm. C) Model for the role of TBC1D14 and the TRAPP complex in mammalian autophagy and ATG9 traffic. Recycling endosomes harbour a population TBC1D14 bound to RAB11, and a population of ATG9 molecules which may traffic to and from the ATG9 compartment. (i) Upon amino acid starvation, TBC1D14 and RAB11 induce a vesicle trafficking step from RAB11 to RAB1 positive membranes at a tubulo-vesicular transport intermediate (ii). This results in recycling of ATG9 to RAB1-regulated Golgi compartments (iii) from where ATG9 can be trafficked to the ATG9 compartment in an ULK1 dependent manner (iv). This maintains the ATG9 compartment under starvation, which can then both contribute to, and promote autophagosome formation from other membrane sources, including the RAB11 positive recycling endosome (v).
Figure 6(A) In Acinetobacter and B. thailandensis, cells in close contact with other cells can initiate membrane complex formation followed by assembly of a few rings of T6SS at the site of contact, which later may continue to assembly of a full-length sheath. Several membrane complexes may form at the same contact site, which can lead to multiple sheath assemblies at the same time. (B) Cells sense contact with proximal cells through a cascade dependent on the presence of TslA and OmpA. Possible interaction of TslA with TssM triggers membrane complex/baseplate assembly followed by the formation of a few sheath rings. TssA caps such sheath foci for further polymerization upon unknown signal. The Hcp tube and VgrG spike along with effectors are propelled out of the cell during sheath contraction. The ATPase ClpV then disassembles the contracted sheath.

Figure 1(A) Schematic diagram of affected proteins and the locations of the point mutations identified in: EARS2 p.Gly110Ser, p.Gly224Ser, p.Arg516Gln, p.Arg120Trp, p.Gln199Arg and p.Ala88Glu mutations-catalytic and anticodon binding domain of the protein; TRMU p.Tyr301Cys and p.Ala10Ser- amino terminal catalytic and carboxy terminal β-barrel domain; QRSL1 p.Val229Gly -amidase signature domain; GOT2 p.Gly188Ser and p.Lys364Glu located in the large catalytic and small catalytic domains and GLS p.Ala432Ser found in the central glutaminase domain. Multiple sequence alignment of the above mentioned proteins shows the conservation of the affected amino acids across species using Jalview software. Analysis was performed using protein sequences from human (Q5JPH6, O75648, Q9H0R6, P00505, O94925), mouse (Q9CXJ1, Q9DAR5, Q9CZN8, P05202, D3Z7P3), zebrafish (Q0P499, Q503J2, F1QAJ4, Q7SYK7, Q8JFS4), frog (Q66JG3, F6TJB0, Q0VFI5, Q28F67, F7B417) and chicken (Q5ZJ66, Q5ZKW0, F1NLA0, P00508, A0A1D5PNV1). (B) Schematic diagram of affected proteins showing their contribution to i) mitochondrial protein translation (EARS2 which aminoacylates mt-tRNAGlu and mt-tRNAGln and QRLS1 which transamidates Glu-tRNAGln to form the correctly charged Gln-tRNAGln), ii) amino-acid metabolism (GOT2 which catalyses the interconversion of oxaloacetate and glutamate into aspartate and α-ketoglutarate while GLS metabolizes glutamine to ammonia and glutamate which is further catabolized to the TCA intermediate α-ketoglutarate to fuel the mitochondrial carbon pool) and iii) COX1 assembly and synthesis due to the dual role of MSS51. MSS51 is not included in Figure 1A as the identified mutation in our patients is a frameshift mutation leading to a premature stop codon and most likely no protein being translated.
