Predicted to enable several functions, including kinesin binding activity; protein kinase binding activity; and signaling adaptor activity. Involved in negative regulation of dendrite extension; negative regulation of neuron differentiation; and negative regulation of protein phosphorylation. Predicted to be located in several cellular components, including centriolar satellite; lysosomal membrane; and perinuclear region of cytoplasm. Predicted to be active in cytoplasm. Human ortholog(s) of this gene implicated in hepatocellular carcinoma and liver cirrhosis. Orthologous to human SPAG9 (sperm associated antigen 9). [provided by Alliance of Genome Resources, Apr 2022]
