Predicted to enable beta-catenin binding activity; gamma-catenin binding activity; and microtubule binding activity. Predicted to be involved in several processes, including activation of GTPase activity; negative regulation of canonical Wnt signaling pathway; and negative regulation of microtubule depolymerization. Is active in postsynapse. Human ortholog(s) of this gene implicated in Sotos syndrome 3 and complex cortical dysplasia with other brain malformations. Orthologous to human APC2 (APC regulator of WNT signaling pathway 2). [provided by Alliance of Genome Resources, Apr 2022]
