Predicted to enable phosphatidylinositol phosphate binding activity; phosphatidylinositol-3,4-bisphosphate binding activity; and retromer complex binding activity. Predicted to be involved in protein localization to endosome and retrograde transport, endosome to Golgi. Predicted to act upstream of or within protein transport. Part of WASH complex. Is expressed in several structures, including extraembryonic component; liver; and neural retina. Orthologous to human WASHC2A (WASH complex subunit 2A) and WASHC2C (WASH complex subunit 2C).
