Predicted to be involved in mitotic sister chromatid segregation. Predicted to act upstream of with a negative effect on transcription by RNA polymerase II. Predicted to act upstream of or within erythrocyte differentiation and inner cell mass cell proliferation. Predicted to be located in nuclear speck. Predicted to be part of condensin complex. Predicted to be active in nucleus. Orthologous to human NCAPG2 (non-SMC condensin II complex subunit G2). [provided by Alliance of Genome Resources, Apr 2022]
