Enables histone deacetylase binding activity and ubiquitin protein ligase activity. Involved in several processes, including mitotic G2 DNA damage checkpoint signaling; protein stabilization; and response to ionizing radiation. Predicted to be located in several cellular components, including actin cytoskeleton; nucleoplasm; and plasma membrane. Predicted to be active in centriole; centrosome; and cytosol. Orthologous to human C10orf90 (chromosome 10 open reading frame 90). [provided by Alliance of Genome Resources, Apr 2022]
