Predicted to enable signaling receptor binding activity. Predicted to be involved in several processes, including positive regulation of canonical Wnt signaling pathway; positive regulation of dendritic spine morphogenesis; and positive regulation of nitrogen compound metabolic process. Predicted to be located in several cellular components, including centrosome; mitochondrion; and nucleoplasm. Predicted to be part of receptor complex. Orthologous to human CAPRIN2 (caprin family member 2). [provided by Alliance of Genome Resources, Apr 2022]
