Example sentences for: antizyme

How can you use “antizyme” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • 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.

  • 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.

  • 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).

  • 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.
