Probable lipase that recruits the AP-1-related (AP-1R) complex to membranes via interaction with APM2 (PubMed:26658609). The AP-1R complex is an adapter protein complex that mediates of cargo protein SNC1 sorting in clathrin-coated vesicles (PubMed:26658609). Interacts with RPP0 (PubMed:15286401). Interacts with APM2 (PubMed:26658609). Present with 1110 molecules/cell in log phase SD medium. Belongs to the TMCO4 family.
