Predicted to enable sequence-specific DNA binding activity. Predicted to be involved in several processes, including positive regulation of cardiac muscle hypertrophy; regulation of barbed-end actin filament capping; and regulation of macromolecule biosynthetic process. Predicted to be located in axon and cytosol. Predicted to be part of F-actin capping protein complex. Predicted to be active in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Used to study congestive heart failure and hypertrophic cardiomyopathy. Orthologous to human MTPN (myotrophin). [provided by Alliance of Genome Resources, Apr 2022]
