CC -!- FUNCTION: Exhibits adenosine 5'-monophosphoramidase activity,
CC hydrolyzing purine nucleotide phosphoramidates with a single phosphate
CC group such as adenosine 5'monophosphoramidate (AMP-NH2) to yield AMP
CC and NH2 (By similarity). Hydrolyzes adenosine 5'monophosphomorpholidate
CC (AMP-morpholidate) and guanosine 5'monophosphomorpholidate (GMP-
CC morpholidate) (By similarity). Hydrolyzes lysyl-AMP (AMP-N-epsilon-(N-
CC alpha-acetyl lysine methyl ester)) generated by lysine tRNA ligase, as
CC well as Met-AMP, His-AMP and Asp-AMP, lysyl-GMP (GMP-N-epsilon-(N-
CC alpha-acetyl lysine methyl ester)) and AMP-N-alanine methyl ester (By
CC similarity). Can also convert adenosine 5'-O-phosphorothioate and
CC guanosine 5'-O-phosphorothioate to the corresponding nucleoside 5'-O-
CC phosphates with concomitant release of hydrogen sulfide (By
CC similarity). In addition, functions as scaffolding protein that
CC modulates transcriptional activation by the LEF1/TCF1-CTNNB1 complex
CC and by the complex formed with MITF and CTNNB1 (By similarity).
CC Modulates p53/TP53 levels and p53/TP53-mediated apoptosis. Modulates
CC proteasomal degradation of target proteins by the SCF (SKP2-CUL1-F-box
CC protein) E3 ubiquitin-protein ligase complex (By similarity). Also
CC exhibits SUMO-specific isopeptidase activity, deconjugating SUMO1 from
CC RANGAP1 and RGS17 (By similarity). {ECO:0000250|UniProtKB:P49773,
CC ECO:0000250|UniProtKB:P70349}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=adenosine 5'-phosphoramidate + H2O = AMP + NH4(+);
CC Xref=Rhea:RHEA:67916, ChEBI:CHEBI:15377, ChEBI:CHEBI:28938,
CC ChEBI:CHEBI:57890, ChEBI:CHEBI:456215;
CC Evidence={ECO:0000250|UniProtKB:P49773};
CC -!- SUBUNIT: Homodimer (By similarity). Interacts with CDK7 (By
CC similarity). Interacts with RUVBL1 and RUVBL2 and is associated with
CC the LEF1/TCF1-CTNNB1 complex and with a KAT5 histone acetyltransferase
CC complex (By similarity). Identified in a complex with MITF and CTNNB1
CC (By similarity). Interacts with CDC34 and RBX1, and is part of a SCF
CC (SKP2-CUL1-F-box protein) E3 ubiquitin-protein ligase complex (By
CC similarity). Interacts with SUMO1, SUMO2 and RGS17 (By similarity).
CC Interacts with the Ten-1 ICD form of TENM1 (By similarity). Interacts
CC with CALM1; interaction increases in the presence of calcium ions (By
CC similarity). {ECO:0000250|UniProtKB:P49773,
CC ECO:0000250|UniProtKB:P70349}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P49773}. Nucleus
CC {ECO:0000250|UniProtKB:P49773}.
CC -!- SIMILARITY: Belongs to the HINT family. {ECO:0000305}.
