HINT1 hydrolyzes purine nucleotide phosphoramidates with a single phosphate group.[7] In addition, functions as scaffolding protein that modulates transcriptional activation.[8]
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.[9][10] 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.[10][11]
