Predicted to enable identical protein binding activity. Predicted to be involved in mRNA splicing, via spliceosome; mitotic spindle assembly checkpoint signaling; and protein localization to kinetochore. Predicted to be located in nuclear speck. Predicted to be part of U2-type precatalytic spliceosome. Predicted to be active in nucleus. Predicted to colocalize with mitotic spindle pole and nuclear chromosome. Orthologous to human IK (IK cytokine). [provided by Alliance of Genome Resources, Apr 2022]
