TMOD4 is a member of tropomodulin (Tmod) family proteins which are capping proteins binding to the pointed end of actin filaments and preventing both elongation and depolymerization. Four mammalian Tmod genes have been identified to date. Tomd1 is expressed in terminally-differentiated post-mitotic cells, like heart, brain, lens, vasculature, and erythrocytes; Tmod2 expressed in neurons; Tmod3 expressed ubiquitously; Tmod4 expressed only in skeletal muscles. This antibody was raised against the full-length human TMOD4 and may cross-react with other Tmods.
