Example sentences for: antizyme
How can you use “antizyme” in a sentence? Here are some example sentences to help you improve your vocabulary:
They are: two ubiquitin precursors UBA80 (clone 1) and UBA52 (clone 21), the ornithine decarboxylase antizyme (Az) (clone 15) and the proteasome β subunit HsN3 (clone 18).
The 26S proteasome is responsible for the bulk turnover of cytoplasmic and nuclear proteins in eukaryotic cells and also plays a key role in the regulation of cell cycle, signal transduction, transcription as well as antigen presentation [ 17 18 19 20 21 ] . Most of the known proteasomal substrates are marked and targeted to proteasome by ubiquitination [ 17 19 20 ] . Ubiquitination, however, is not an obligatory step for substrate targeting to proteasome [ 17 18 20 ] . The degradation of the ornithine decarboxylase (ODC), the rate-limiting enzyme for polyamine synthesis, involves a protein named antizyme (Az), which binds and targets ODC to 26S proteasome for degradation [ 18 ] . However, ODC has remained an "orphan" in Az-dependent proteasomal degradation.
The best-characterized example of ubiquitin-independent degradation is the degradation of ornithine decarboxylase (ODC), which is dependent upon ODC interaction with the targeting protein antizyme (Az) [ 18 ] . How ubiquitinated substrates or Az-bound ODC is recognized by the 26S proteasome is not well understood.
This report has focused upon the functional characterization of two proteins that function along the degradation pathways of the 26S proteasome: antizyme (Az) and HsN3.
