Histidine triad nucleotide-binding protein 1 also known as adenosine 5'-monophosphoramidase is an enzyme that in humans is encoded by the HINT1 gene.

HINT1 hydrolyzes purine nucleotide phosphoramidates with a single phosphate group. In addition, functions as scaffolding protein that modulates transcriptional activation.

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. 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.
