Example sentences for: oligomerization
How can you use “oligomerization” in a sentence? Here are some example sentences to help you improve your vocabulary:
The initial step of the insertion can proceed in the presence of either Mg.ATP or a non-hydrolyzable ATP-analog and involves oligomerization of the BchD and BchI subunits to form an oligomeric ring of AAA protomers that resembles the ring structure of NSF and other AAA proteins [ 14 32 ] . The second step of the insertion involves an obligatory hydrolysis of ATP that is tightly coupled with the transfer of the chelated Mg 2+to the protoporphyrin ring by BchH [ 49 ] . Although the details differ from midasin, particularly with respect to the subunit composition of the AAA ring, this chelation reaction provides a structural model suggesting that the function of the midasin M-domain may be to regulate the ATPase activity of the AAA protomers in the pseudo-hexameric ring and thus couple ATP hydrolysis to the binding of a protein ligand at the MIDAS site.
Fas contains a single transmembrane domain and belongs to the tumor necrosis factor (TNF)/nerve growth factor family [ 8 ] . FasL contains a single transmembrane domain and is also a member of the same TNF family [ 9 ] . A soluble form of FasL has been described, but appears to be less capable of inducing apoptosis, when compared with the bound form [ 10 11 ] . The binding of FasL with Fas initiates receptor oligomerization, which recruits Fas-associated death domain (FADD) [ 12 ] . FADD binds procaspase-8 and permits activation of caspase-8 through self-cleavage [ 13 ] . Caspase-8 activates the effector caspases, which commits the cell to the orderly process of apoptosis [ 14 15 ] . In addition, caspase-8 cleaves Bcl-2-interactive-death-agonist (Bid) [ 16 ] . Truncated Bid localizes to the mitochondria and promotes cytochrome c release; this process also serves as a major apoptotic-signaling pathway for Fas [ 16 17 18 ] . Depending upon the amount of caspase-8 that is activated, the predominant pathway can be either Bid cleavage with subsequent mitochondrial release of cytochrome c or activation of the effector caspase pathway [ 18 ] . Resident cells of the kidney express both Fas and FasL and Fas/FasL signaling is functional in these cells [ 19 20 21 22 23 24 ] . A recent review by Ortiz and associates [ 25 ] noted that the combined literature demonstrating participation of Fas/FasL pathway in renal injury essentially fulfilled Koch's postulates.
Although the energy required for lateral separation of the transmembrane domains in membrane appears to be high, the third step in Figure 1 (clustering via transmembrane domain oligomerization) may compensate for it.
The N-terminal core region of high similarity between family members correlates to a region in nucleophosmin/B23 that has been shown to be involved in oligomerization as well as chaperone activity [ 44 ] . A central portion between nucleophosmin's two acidic domains is required for ribonuclease activity [ 44 ] ; this region does not have a corresponding domain in either NPM3 or nucleoplasmin, suggesting that these proteins would lack such activity.
SAM domain oligomerization is the key event that triggers a variety of leukemias [ 21 ] and is therefore an attractive target for therapeutic intervention.
