Figure Lengend Snippet: (A) Schematic diagram of membrane fractionation using differential centrifugation and sucrose gradient centrifugation to separate ERGIC-enriched L fraction and ER-enriched P fraction followed by co-immunoprecipitation. (B) Co-IP (Co-immunoprecipitation) assay performed with the ERGIC-enriched fraction (L) and the ER-enriched fraction (P) extracted from HEK293T cells expressing HA-TMED10, without or with TMED10-V5 co-expression using anti-V5 agarose. (C) Quantification of the association efficiency of TMED10-V5 with other subfamily members (TMED2, 5, 9) or HA-TMED10 (mean ± SEM) as shown in (B); p values were calculated by two-way ANOVA (n = 3). (D) Co-IP assay was performed with HEK293T cells co-expressing TMED10-V5 and HA-TMED10 without or with GFP-Rab1A (R1A) or GFP-Rab1B (R1B) using anti-V5 agarose. (E) Quantification of the association efficiency of TMED10-V5 with other subfamily members (TMED2, 5, 9) or HA-TMED10 (mean ± SEM) as shown in (D); p values were calculated by two-way ANOVA (n = 3). (F) Turnover of TMED10-V5 in CHX chase assay without or with mIL-1β-FLAG or its UcPS-deficient mutant mIL-1β-WY-LL or three other subfamily members (HA-TMED2, 5, 9) expression in TMED10 KO HeLa cells. (G) Quantification of normalized TMED10-V5 (mean ± SEM) as shown in (F), the relative level of TMED10-V5 was normalized to Tubulin and the 0 h control group was set as 1; p values were calculated by two-way ANOVA (n ≥ 3). (H) Turnover of TMED10-V5 in CHX chase assay without or with mIL-36α, mIL-36α-F10A and HA-TMED2, 5, 9 expression in TMED10 KO HeLa cells. (I) Quantification of normalized TMED10-V5 (mean ± SEM) as shown in (H); p values were calculated by two-way ANOVA (n ≥ 2). (J) Turnover of TMED10-V5 in CHX chase assay without or with RAB1A, RAB1A UcPS-deficient mutant T75D and HA-TMED2, 5, 9 expression in TMED10 KO HEK293T cells. (K) Quantification of normalized TMED10-V5 (mean ± SEM) as shown in (J); p values were calculated by two-way ANOVA (n = 4). (L) Turnover of TMED10-V5 in CHX chase assay without or with RAB1B, RAB1B UcPS-deficient mutant T72D and HA-TMED2, 5, 9 expression in TMED10 KO HEK293T cells. (M) Quantification of normalized TMED10-V5 (mean ± SEM) as shown in (L); p values were calculated by two-way ANOVA (n = 4). (N) Model showing two distinct populations of TMED oligomers exist in cellular trafficking pathway. TMED hetero-oligomers play a role in conventional cargo (e.g. GPI-anchored proteins) transport between ER and ERGIC, while TMED homo-oligomers mediate unconventional secretion cargo translocation at the ERGIC. UcPS cargo stabilizes the homo-oligomeric structures, which subsequently facilitates translocation. ns, non-significant; *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001.
