How can you use “phosphorylates” in a sentence? Here are some example sentences to help you improve your vocabulary:
In response to DNA damage induced by ionizing radiation or chemical agents such as cisplatin, ATM kinase is activated and phosphorylates a number of downstream regulatory proteins important for cell cycle arrest, growth control, apoptosis and DNA repair [ 25 26 27 28 ] . AT patients are known to be predisposed to a variety of cancers, and the fibroblasts of AT patients are hypersensitive to ionizing radiation [ 29 ] . Although many reports showed the association of ATM mutation with risk of a number of different human malignancies, including prostate cancer, breast cancer, ovarian cancer, B-cell chronic lymphocytic leukemia and mantle cell lymphoma, the underlying molecular mechanism by which ATM gene causes these changes are not well understood [ 30 31 32 33 34 35 ] . There is so far no study showing the association of ATM gene with any solid tumor.
A key question is whether DNA-PK or some other kinase phosphorylates serine 37 of p53 in vivo.
P-TEFb phosphorylates the carboxy-terminal domain of the RNA polymerase II complex [ 12], facilitating transcription elongation.
This putative association is strengthened by finding for the first time that targeting of RIα requires the AKAP binding surface [ 17 ] . Yotiao is another AKAP enriched at the NMJ, but appears to bind only RII [ 30 ] . PKA phosphorylates the nAChR when stimulated at the synapse by the neuropeptide CGRP and by adenosine from muscle responding to acetylcholine [reviewed by [ 31 ] ]. This phosphorylation may regulate the degradation of the nAChR [ 32 ] . Consistent with the action at the presynapse, it was shown that PKA facilitation of acetylcholine release is dependent on nerve endplate calcium concentration [ 33 ] . Based on our observation of colocalization with synaptophysin at presynaptic vesicles, RIα may be the isotype that influences this release of neurotransmitter.
When recruited to stalled transcription complexes, P-TEFb phosphorylates serines at position 2 in the CTD [8], the Spt5 subunit of DSIF [9], and the RD subunit of NELF [10].
