Predicted to enable protein homodimerization activity. Predicted to be involved in several processes, including Golgi reassembly; establishment of Golgi localization; and intrinsic apoptotic signaling pathway in response to hydrogen peroxide. Predicted to act upstream of or within several processes, including Golgi localization; positive regulation of axonogenesis; and protein phosphorylation. Located in Golgi membrane. Orthologous to human STK25 (serine/threonine kinase 25). [provided by Alliance of Genome Resources, Apr 2022]
