Abstract
Adhesion G Protein-coupled Receptor G1 (G1), previously known as GPR56, plays a role in a wide variety of biological functions including cancer, immunology, and development. Mutations in G1 cause the brain developmental disorder Bilateral Fronto-Parietal Polymicrogyria (BFPP), and mutant forms of G1 associated with BFPP exhibit reduced cell surface expression and signaling. Sorting Nexin (SNX) family members typically modulate endosomal trafficking to the plasma membrane, and SNX27 has been recently identified as a potential modulator of G1 in a proteomic study. I showed that SNX27 interacts with both full-length G1 and N-terminally truncated G1 in HEK-293 cells. I also found that SNX27 increases total and surface expression of G1 and N-terminally truncated G1. Preliminary results indicate that SNX27 increases signaling of G1. Based on these results, SNX27 may be an important modulator of G1 expression and signaling in vivo.
