Plays a role in cortical progenitor cell proliferation and differentiation (PubMed:27404227). Promotes dendritic spine development of post-migratory cortical projection neurons by modulating the beta-catenin signaling pathway (PubMed:27404227). Interacts with CCDC85B (PubMed:27404227). Expressed in brain (at protein level) (PubMed:27404227). Expressed in neural progenitor cells and postmitotic neurons of the embryonic cerebral cortex (PubMed:27404227). Expressed in the embryonic cortex and germinal ventricular zone (PubMed:27404227). Expressed in cells of the cortical plate and in retinal pigment epithelium and lens between 12 and 14 dpc (at protein level) (PubMed:27404227). Belongs to the EURL family.
