Predicted to enable chromatin DNA binding activity. Predicted to be involved in negative regulation of transmembrane receptor protein serine/threonine kinase signaling pathway and nuclear envelope organization. Predicted to act upstream of or within several processes, including blood vessel endothelial cell migration involved in intussusceptive angiogenesis; regulation of extracellular matrix organization; and skeletal muscle cell differentiation. Predicted to be located in nuclear inner membrane. Predicted to be integral component of membrane. Predicted to be integral component of nuclear inner membrane.
