FAU (gene)

40S ribosomal protein S30 is a is_associated_with::protein that in humans is encoded by the FAU is_associated_with::gene.

Function
This gene is the cellular homolog of the fox sequence in the is_associated_with::Finkel-Biskis-Reilly murine sarcoma virus (FBR-MuSV). It encodes a fusion protein consisting of the is_associated_with::ubiquitin-like protein is_associated_with::fubi at the is_associated_with::N-terminus and ribosomal protein S30 at the is_associated_with::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. Pseudogenes derived from this gene are present in the genome. Similar to ribosomal protein S30, ribosomal proteins S27a and L40 are synthesized as fusion proteins with ubiquitin.
