FUSION GENES

DNA/RNA

Description

spans at least 42 kb; 13 exons

Proteins

Function

Tropomyosins are actin-binding proteins; component of cytoskeletal microfilaments; tropomyosins mediate the effect of Ca2+ on the myosin-actin interaction In skeletal muscles, but their function in smooth muscles and other tissues is yet unknown

Homology

Other tropomyosins: TPM1 (alpha) located in 15q22, TPM2 (beta), located in 9q13, and TPM4 located in 19p13.1

Implicated in

Entity name
rare cases of ALK+ anaplasic large cell lymphoma (ALCL) with t(1;2)(q25;p23)
Disease
ALCL presents as an aggressive lymphoma with systemic signs
Prognosis
nonetheless, have a favourable prognosis
Hybrid gene
5 CLTC - 3 ALK
Fusion protein
104 kDa ; 221 N-term amino acids from TPM3 fused to the 562 C-term amino acids from ALK (i.e. the entire cytoplasmic portion of ALK with the tyrosine kinase domain); homodimerization of the fusion protein.
Oncogenesis
TPM3-ALK is contitutively activated
Entity name
cases of Inflammatory myofibroblastic tumors with t(1;2)(q25;p23)
Disease
rare soft tissue tumour found in children and young adults
Prognosis
good prognosis
Hybrid gene
5 CLTC - 3 ALK
Fusion protein
104 kDa ; 221 N-term amino acids from TPM3 fused to the 562 C-term amino acids from ALK (i.e. the entire cytoplasmic portion of ALK with the tyrosine kinase domain); homodimerization of the fusion protein.
Oncogenesis
TPM3-ALK is contitutively activated
Entity name
papillary thyroid carcinoma
Disease
represents about 60% of thyroid cancers; small, undetectable, chromosome 1q inversions have shown to produce a TPM3-NTRK1 hybrid gene in a very few cases of papillary thyroid carcinoma.
Prognosis
prognosis of papillary thyroid carcinoma is excellent
Hybrid gene
5 TPM3 - 3 NTRK1
Fusion protein
221 N-term amino acids from PM3 fused to the C-term of NTRK1, including its tyrosine kinase domain
