**Background of Human SLC15A3 Protein**
SLC15A3. a member of the solute carrier family 15 (SLC15), encodes a proton-coupled oligopeptide transporter predominantly expressed in immune cells, particularly within endolysosomal compartments. Functioning as an influx transporter, SLC15A3 facilitates the uptake of di-/tripeptides and bacterial degradation products, such as muramyl dipeptide (MDP), by coupling substrate movement with protons. This activity links it to innate immune signaling pathways, including Toll-like receptor (TLR) and NOD-like receptor (NLR) systems, where it may modulate inflammatory responses by shuttling pathogen-associated molecular patterns (PAMPs) for immune recognition.
Genomic studies suggest SLC15A3 involvement in autoimmune and infectious diseases. For instance, it has been associated with lupus pathogenesis through interactions with type I interferon signaling. Structurally, SLC15A3 contains 12 transmembrane domains, typical of SLC15 family members, but exhibits distinct substrate preferences compared to its homologs (e.g., SLC15A4). Recent research highlights its potential as a therapeutic target for immune disorders or drug delivery systems. However, precise mechanisms regulating its activity, tissue-specific roles, and broader physiological implications remain under exploration, necessitating further functional and clinical studies.
