Figure 1. The cytosolic sequence of LAMP2C interacts with RNA-binding proteins. (A) Identity levels of the cytosolic sequences of fly and nematode LAMPs to that of human LAMP2s. (B) A schematic representation of biotin-conjugated peptides. (C) Proteins that interact with the cytosolic sequences of LAMP2s were analyzed by pull-down assay followed by LC-MS/MS analysis of LAMP2C peptide-interacting proteins. (D) Expression levels of Lamp2c mRNA in mouse tissues. Values are the means ± SE (n = 3 to 4). (E) Pull-down assay and LC-MS/MS analysis of LAMP2C peptide-interacting proteins from mouse brain. The distribution of the identified proteins is shown.
