Based on limited published evidence, XKR7 is a plasma membrane-associated protein involved in apoptotic processes. According to UniProt annotations and GO terms, XKR7 functions in protein binding, apoptotic cell development, engulfment of apoptotic cells, and phosphatidylserine exposure on apoptotic cell surfaces. Recent research identified XKR7 as a target in the miR-660-5p/XKR7 regulatory axis within gingival fibroblast-derived exosomes, where it is associated with apoptosis regulation 1.
