UniProt functional annotation for P49773



	UniProt functional annotation for P49773

UniProt code: P49773.

Organism: Homo sapiens (Human).

Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.

Function: Hydrolyzes purine nucleotide phosphoramidates with a single phosphate group, including adenosine 5'monophosphoramidate (AMP-NH2), adenosine 5'monophosphomorpholidate (AMP-morpholidate) and guanosine 5'monophosphomorpholidate (GMP-morpholidate). Hydrolyzes lysyl-AMP (AMP-N-epsilon-(N-alpha-acetyl lysine methyl ester)) generated by lysine tRNA ligase, as well as Met-AMP, His-AMP and Asp-AMP, lysyl-GMP (GMP-N-epsilon-(N-alpha-acetyl lysine methyl ester)) and AMP-N-alanine methyl ester. Can also convert adenosine 5'-O-phosphorothioate and guanosine 5'-O-phosphorothioate to the corresponding nucleoside 5'-O- phosphates with concomitant release of hydrogen sulfide. In addition, functions as scaffolding protein that modulates transcriptional activation by the LEF1/TCF1-CTNNB1 complex and by the complex formed with MITF and CTNNB1. Modulates p53/TP53 levels and p53/TP53-mediated apoptosis. Modulates proteasomal degradation of target proteins by the SCF (SKP2-CUL1-F-box protein) E3 ubiquitin-protein ligase complex. {ECO:0000269|PubMed:15703176, ECO:0000269|PubMed:16014379, ECO:0000269|PubMed:16835243, ECO:0000269|PubMed:19112177, ECO:0000269|PubMed:22329685, ECO:0000269|PubMed:22647378, ECO:0000269|PubMed:9323207}.

Subunit: Homodimer. Interacts with CDK7. Interacts with RUVBL1 and RUVBL2 and is associated with the LEF1/TCF1-CTNNB1 complex and with a KAT5 histone acetyltransferase complex. Identified in a complex with MITF and CTNNB1. Interacts with CDC34 and RBX1, and is part of a SCF (SKP2-CUL1-F-box protein) E3 ubiquitin-protein ligase complex. {ECO:0000269|PubMed:16014379, ECO:0000269|PubMed:16835243, ECO:0000269|PubMed:17337452, ECO:0000269|PubMed:19112177, ECO:0000269|PubMed:22329685, ECO:0000269|PubMed:22647378, ECO:0000269|PubMed:22869114, ECO:0000269|PubMed:8643579, ECO:0000269|PubMed:9323207}.

Subcellular location: Cytoplasm. Nucleus. Note=Interaction with CDK7 leads to a more nuclear localization.

Tissue specificity: Widely expressed.

Disease: Neuromyotonia and axonal neuropathy, autosomal recessive (NMAN) [MIM:137200]: An autosomal recessive neurologic disorder characterized by onset in the first or second decade of a peripheral axonal neuropathy predominantly affecting motor more than sensory nerves. The axonal neuropathy is reminiscent of Charcot-Marie-Tooth disease type 2 and distal hereditary motor neuropathy. Individuals with NMAN also have delayed muscle relaxation and action myotonia associated with neuromyotonic discharges on needle EMG resulting from hyperexcitability of the peripheral nerves. {ECO:0000269|PubMed:16835243, ECO:0000269|PubMed:22961002}. Note=The disease is caused by variants affecting the gene represented in this entry.

Similarity: Belongs to the HINT family. {ECO:0000305}.
