Enables peptidase activity. Involved in Golgi to plasma membrane protein transport and retrograde transport, endosome to Golgi. Located in Golgi apparatus and cytoskeleton. Colocalizes with trans-Golgi network. Is expressed in several structures, including diaphragm; nervous system; retina; tongue; and vertebral axis musculature. Human ortholog(s) of this gene implicated in congenital myasthenic syndrome 22. Orthologous to human PREPL (prolyl endopeptidase like). [provided by Alliance of Genome Resources, Apr 2022]
