| DNA/RNA |
| Transcription | 1776 bp mRNA; transcribed in a centromeric to telomeric orientation |
| Protein |
| Description | 591 amino acids, 64 kDa; two functional domains separated by a linker region with a dimerization domain (amino acids 170 to 199): amino acids 1 to 169 encode the IMP cyclohydrolase (IMPCH) function, and amino acids 200 to 591 encode the 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase (AICARFT) function; homodimer |
| Expression | wide |
| Function | bifunctional purine biosythesis:9th and 10th step of the de novo purine synthesis |
| Homology | belongs to the PURH family |
| Implicated in |
| Entity | inv(2)(p23q35) --> ATIC- ALK |
| Disease | found in rare cases of ALK+ anaplasic large cell lymphoma |
| Cytogenetics | hidden translocation most often |
| Hybrid/Mutated Gene | 5' ATIC - 3' ALK |
| Abnormal Protein | 791 amino acids, 87 kDa. 229 N-term amino acid from ATIC containing the IMPCH domain and the dimerization domain fused to the 562 C-term amino acids from ALK (i.e. the entire cytoplasmic portion of ALK with the tyrosine kinase domain); cytoplasmic localisation only. |
| Oncogenesis | ATIC seems to provoke the dimerization of ATIC-ALK, which should lead to constitutive autophosphorylation and activation of the ALK tyrosine kinase, as for NPM1-ALK (see t(2;5)(p23;q35) ). |
