Membrane:Article Title: KRAP regulates mitochondrial Ca2+ uptake by licensing IP3 receptor activity and stabilizing ER-mitochondrial junctions.
Article Snippet: Imaging dishes were from Cellvis (Gerasdorf bei Wein, Austria). .. Plasmids encoding the following proteins were used: TOM20 [translocase of outer (mitochondrial) membrane 20, also known as TOMM20] tagged to GFP (TOM20–GFP) (Prole and Taylor, 2019a), Mito-R-GECO1 (Addgene, #46021) (Wu et al., 2013), human KRAP with an N-terminal myc-DDK tag (OriGene, Rockville, MD, USA, #RC205550) and siRNA-resistant human KRAP with an N-terminal myc-DDK tag (Thillaiappan et al., 2021). .. The following antibodies were used for western blotting (WB), immunocytochemistry (IC), or PLAs: anti-KRAP (rabbit polyclonal; ProteinTech, Manchester, UK, #14157-1-AP, RRID:AB_2195472; WB 1:1000), ChromoTek GFP-Booster ATTO488 (nanobody; Chromotek, Planegg-Martinsried, Germany #gba488; RRID: AB_2631386; IC 1:500), anti-MCU (rabbit polyclonal; Thermo Fisher Scientific, PA5-109304, RRID: AB_2854715; WB 1:1000), anti-β-actin (mouse monoclonal; Cell Signaling Technology, Leiden, Netherlands, #8H10D10, RRID:AB_2242334; WB 1:20,000), IRDye 680RD goat anti-mouse IgG secondary antibody (LI-COR, 926-68070, RRID:AB_10956588; WB 1:10,000), horseradish peroxidase (HRP)-conjugated sheep anti-rabbit IgG H&L (Abcam, ab6795, RRID: AB_955446; WB 1:10,000), Alexa Fluor 568-conjugated goat anti-rabbit IgG (H+L) (Thermo Fisher Scientific, A-11011, RRID:AB_143157; WB 1:10,000), Alexa Fluor 488-conjugated goat anti-rabbit IgG (H+L) (Thermo Fisher Scientific, A-11008, RRID:AB_143165; WB 1:10,000), Alexa Fluor 568-conjugated goat anti-mouse IgG (H+L) (Thermo Fisher Scientific, A21235, RRID:AB_2535804; WB 1:10,000), anti-VDAC1 (Abcam, ab14734, RRID:AB_443084; PLA 1:400), anti-GFP (Abcam, ab290, RRID: AB_303395; PLA 1:200, WB 1:1000) and anti-TOM20 (Abcam, ab56783, RRID:AB_945896;WB1:1000).
