Predicted to enable protein kinase binding activity and protein tyrosine phosphatase activity. Predicted to be involved in several processes, including early endosome to late endosome transport; positive regulation of adherens junction organization; and positive regulation of transport. Predicted to act upstream of or within cell projection organization and protein transport. Predicted to be located in ciliary basal body; early endosome; and nuclear body. Is expressed in several structures, including alimentary system; central nervous system; gonad; respiratory system epithelium; and skin. Orthologous to human PTPN23 (protein tyrosine phosphatase non-receptor type 23). [provided by Alliance of Genome Resources, Apr 2022]
