Example sentences for: proteasomes
How can you use “proteasomes” in a sentence? Here are some example sentences to help you improve your vocabulary:
A small protein Ump1 associates with the premature proteasome complexes and is shown to be involved in assisting the maturation of 20S proteasome, possibly by interacting with the β rings of half proteasomes [ 46 ] . Upon the maturation of the 20S proteasome, Ump1 is trapped inside the proteasome and is degraded by proteasome [ 46 ] . The HSP70 like chaperon protein Hsc73 also associates with the 16S proteasome precursor complexes [ 35 36 ] . The exact role of Hsc73 in 16S precursor proteasome complex is not known, but has been suggested to assist proteasome maturation [ 35 36 ] . Our studies add Smad1, Smad1 interacting proteins such as SNIP1, Smad4, and Az as additional proteins that associate with the assembly intermediates.
Second, the final maturation of the 20S proteasome resulted from the assembly of two half proteasomes into the four stacked ring structure could trap the already bound Smad1 inside the proteasome for rapid degradation or lead to the dissociation of Smad1 from mature 20S proteasome due to the inaccessibility of Smad1 binding site on the incorporated HsN3.
In a recent large-scale screen with 1739 yeast proteins used as bait [ 3 ] , midasin (YLR106p) was identified in the polypeptide sets that copurified with four bait proteins, ESS1p, RPT1p, YML029p and HRT1p, that function principally in RNA metabolism and in the regulation of proteasomes (which are mostly intranuclear in yeast [ 50 ] ). However, the interpretation of these proteomic data is clouded by the fact that no protein partners were identified in the complementary experiment in which midasin was itself used as bait.
Proteasomes translocated to meiotic spindles of rat oocytes and MG-132 induced-inhibition of proteasomal activity resulted in partial segregation of chromosomes during meiosis I [ 42 ] . Moreover, defective proteasomal activity in fission yeast impaired chromosome segregation [ 38 ] .
The half proteasomes containing one α and one β rings are further assembled into 20S proteasome, a process involving the proteolytic cleavage of the prosequences of five β subunits, including HsN3.
