Overview:

TPM3 is a member of the tropomyosin family of actin-binding proteins which are dimers of coiled-coil proteins that provide stability to actin filaments and regulate access of other actin-binding proteins. Mutations in TPM3 gene result in autosomal dominant nemaline myopathy and other muscle disorders (1). TPM3 gene locus is involved in translocations with other loci including c-ros oncogene 1 (ROS1) which result in the formation of the TPM3-ROS1 fusion protein that act as an oncogene. TPM3-ROS1 fusion gene product has been detected in lung adenocarcinoma is higher in lung adenocarcinoma with wild-type EGFR (2).

Gene Aliases:

TPM3: CAPM1; CFTD; hscp30; NEM1; OK/SW-cl.5; TM-5; TM3; TM30; TM30nm; TM5; TPMsk3; TRK
ROS1: c-ros-1; MCF3; ROS
