FunctionBlocks the elongation and depolymerization of the actin filaments at the pointed end. The Tmod/TM complex contributes to the formation of the short actin protofilament, which in turn defines the geometry of the membrane skeleton. May play an important role in regulating the organization of actin filaments by preferentially binding to a specific tropomyosin isoform at its N-terminus.
Tissue specificityHighly expressed in the erythrocyte, heart and skeletal muscle.
Sequence similaritiesBelongs to the tropomodulin family.
