Based on limited published evidence, LRRC24 is a leucine-rich repeat protein localized to the external plasma membrane with predicted signaling receptor activity and roles in synapse assembly regulation. The primary published finding identifies LRRC24 natural antisense RNA within exosomes secreted from colorectal cancer cell lines, which can be transferred to hepatoma and lung cancer cells 1. This suggests potential involvement in intercellular communication through exosomal RNA transfer, though direct protein function remains largely uncharacterized.
