Predicted to enable several functions, including chromatin binding activity; protein kinase B binding activity; and titin binding activity. Predicted to be involved in negative regulation of myoblast differentiation and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including negative regulation of myotube differentiation; regulation of transcription by RNA polymerase II; and skeletal muscle cell differentiation. Predicted to be located in several cellular components, including PML body; euchromatin; and sarcomere. Predicted to be active in nucleus. Predicted to colocalize with I band. Orthologous to human ANKRD2 (ankyrin repeat domain 2). [provided by Alliance of Genome Resources, Apr 2022]
