Histidine triad nucleotide-binding protein 1 is a protein that in humans is encoded by the HINT1 gene.^[3][4] It is a haploinsufficient tumor suppressor gene that inhibits the Wnt/β-catenin pathway in colon cancer cells and Microphthalmia-associated transcription factor (MITF) activity in human mast cells.^[5][6] In the LysRS-Ap4A-MITF signaling pathway, HINT1 inhibits the MITF transcriptional activity by direct association. Upon pathway activation, HINT1 is released from MITF by diadenosine tetraphosphate (Ap4A), produced by LysRS.^[6][7]
