Proteins

Description

248 amino acids, 29 kDa. Coiled-coil structure

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 TPM3 located in 1q25

Implicated in

Entity name
Inflammatory myofibroblastic tumors with t(2;19)(p23;p13.1)
Disease
rare soft tissue tumour found in children and young adults
Prognosis
good prognosis
Hybrid gene
5 CLTC - 3 ALK
Fusion protein
221 N-term amino acids from TPM4 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
TPM4-ALK is contitutively activated
