Enables ATP binding activity; protein C-terminus binding activity; and protein serine/threonine kinase activity. Involved in several processes, including intracellular signal transduction; neuron differentiation; and positive regulation of extrinsic apoptotic signaling pathway in absence of ligand. Located in several cellular components, including actin filament; membrane raft; and nucleus. Orthologous to human DAPK3 (death associated protein kinase 3).
