- Experimental Notes
No prominent immuno-signal for detected by Western blotting on extracts of tested secondary cell lines of human (HeLa, HEK293), murine (RAW), and porcine (PK-15) origin.
HA-tagged FAU ectopically overexpressed in HeLa cells is readily detected using anti-FAU ABIN2798885.
The presumed N-terminal cleavage product (ubiquitin-like modifier FUBI) of the FAU gene (FUBI + ribosomal protein S30) is not expressed in sufficient amounts to be detected by Western blotting. Even using a plasmid vector encoding HA-tagged ubiquitin-like modifier FUBI does not results in a proper expression of this protein.

- Experimental Notes
ABIN2798885 readily immunoprecipitates FAU protein, although overexpression might be required. Expression levels of endogenous FAU in HeLa cells appear to be too low to achieve proper enrichment by immunoprecipitation.
The presumed N-terminal cleavage product (ubiquitin-like modifier FUBI) of the FAU gene (FUBI + ribosomal protein S30) is not expressed in sufficient amounts to be detected by Western blotting. Even using a plasmid vector encoding HA-tagged ubiquitin-like modifier FUBI does not results in a proper expression of this protein.

- 背景
-
Target Description: FUBI is the cellular homolog of the fox sequence in the Finkel-Biskis-Reilly murine sarcoma virus (FBR-MuSV). It is a fusion protein consisting of the ubiquitin-like protein fubi at the N terminus and ribosomal protein S30 at the C terminus. It has been proposed that the fusion protein is post-translationally processed to generate free fubi and free ribosomal protein S30. Fubi is a member of the ubiquitin family, and ribosomal protein S30 belongs to the S30E family of ribosomal proteins. Whereas the function of fubi is currently unknown, ribosomal protein S30 is a component of the 40S subunit of the cytoplasmic ribosome.
