NCIt definition : Human TPM4 wild-type allele is located in the vicinity of 19p13.1 and is approximately
35 kb in length. This allele, which encodes tropomyosin alpha-4 chain protein, plays
a role in both cytoskeletal modeling and smooth muscle cell contraction. A chromosomal
translocation t(2;19)(p23;p13.1) of this gene and the ALK gene is associated with
inflammatory myofibroblastic tumors.;
