mmuTrim21

Trim 21 comes from the family of TRIM. ‘MMu’ means that it is from mouse. It is a known type of E3 ubiquitin-protein ligase as an intracellular antibody effector in the antibody-mediated proteolysis pathway.

Usage and Biology

Trim 21 has a particular domain to recognize the Fc domain and combine with antibody marked no-enveloped virions. Using its E3 ubiquitin-protein ligase activity, trim 21 with the antibody bond to virons is degraded by the Ubiquitin dependent protease degradation pathway.

Due to the organism, therapeutic antibodies targeting disease-associated antigens in extracellular is a key tool for some certain diseases in current researches. Although some diseases is not caused by virons, trim 21 can be used in these diseased by blocking a particular pathogenic process.

Result

To validate the protein degradation efficiency of the ScFv-based ErbB3 Predator system, we transfected MCF7 cells with plasmids expressing ScFvErbB3-linker-Fc fusion protein and HA- Trim21. Western Blotting analysis showed that with the high expression of ScFvErbB3-linker- Fc fusion protein and HA-Trim21, the ErbB3 protein level decreased dramatically in cells transfected with ErbB3 Predator (approximately 30%, Fig 1A and B). This result demonstrated that the ScFv-based Predator system could successfully degrade the targeted membrane protein.
