FunctionE3 UFM1-protein ligase that mediates ufmylation of target proteins such as DDRGK1/C20orf116. The function of ufmylation is unknown. May act as a tumor suppressor by inhibiting cell invasion, blocking NF-kappa-B signaling and increasing stability of CDK5RAP3.
Tissue specificityUbiquitously expressed, with a high expression in liver (at protein level). Low expression in several invasive hepatocellular carcinomas, such HepG2, Hep3B, HLE and PLC.
Sequence similaritiesBelongs to the UFL1 family.
Post-translational modificationsUbiquitinated, leading to its degradation by the proteasome. Interaction with CDK5RAP3 protects each other against ubiquitination and degradation via the proteasome.
Cellular localizationEndoplasmic reticulum. Cytoplasm. In cytoplasm colocalizes with CDK5RAP3.
