Salivary glands or larval samples were made exactly as mentioned in our previous work (Ghosh et al, 2019 (link); Mathre et al, 2019 (link)). Dilutions of antibodies used: 1:4,000 for anti-tubulin (E7-c), (mouse) from DSHB, 1:1,000 for anti-actin antibody (Cat# A5060) (Rabbit) from Sigma-Aldrich, 1:2,000 for anti-GFP antibody (Cat# sc-9996) (Rabbit) from Santa Cruz, 1:1,000 for anti-mCherry antibody (Cat# PA5-34974) (Rabbit) from Thermo Fisher Scientific, 1:1,000 for anti-HA antibody (Cat# 2367S) (Mouse) from CST and Normal Rabbit IgG (sc-2027) from Santa Cruz, 1:1,000 for anti-dPIP4K (generated for the laboratory by NeoBiolab).
