Genes affected

SLC15A4 (HGNC:23090): (solute carrier family 15 member 4) Enables L-histidine transmembrane transporter activity; peptide transmembrane transporter activity; and peptidoglycan transmembrane transporter activity. Involved in several processes, including dipeptide import across plasma membrane; peptidoglycan transport; and positive regulation of toll-like receptor signaling pathway. Located in endolysosome membrane. Is integral component of lysosomal membrane. [provided by Alliance of Genome Resources, Apr 2022]
