| Genes involved and Proteins |
| Gene Name | ALK (anaplastic lymphoma receptor tyrosine kinase) |
| Location | 2p23.2 |
| Protein | 1620 amino acids; 177 kDa; glycoprotein (200 kDa mature protein) ; membrane associated tyrosine kinase receptor |
| Gene Name | TPM4 (tropomyosin) |
| Location | 19p13.12 |
| Protein | 248 amino acids, 29 kDa; coiled coil structure |
| Result of the chromosomal anomaly |
| Hybrid Gene | |
| Description | 5' TPM4 - 3' ALK |
| Fusion Protein | |
| Description | 783 amino acids. N-term TPM4 containing all but its 27 C-term amino acids , including the coiled coil domain, fused to the 562 C-term amino acids from ALK (i.e. the entire cytoplasmic portion of ALK with the tyrosine kinase domain) |
| Expression Localisation | predominantly cytoplasmic |
| Oncogenesis | TPM4-ALK is contituvely activated |
