Words similar to smad-regulated
Example sentences for: smad-regulated
How can you use “smad-regulated” in a sentence? Here are some example sentences to help you improve your vocabulary:
The phosphorylation of Smad1 at the carboxylterminal SSVS motif triggers the release of Smad1 from the receptor, the formation of homo-oligomers of Smad1 and hetero-oligomers of Smad1 and Smad4, and the subsequent nuclear translocation of both Smad1 and Smad4 [ 6 9 10 ] . In the nucleus, Smad1 and Smad4 function as DNA-binding transcriptional regulators [ 9 ] . However, there is a unique feature in Smad-regulated transcription.
The transcriptional regulatory activities of Smad1 in the nucleus are associated with its ability to directly bind to DNA [ 12 ] , its interaction with other DNA-binding transcription factors, such as OAZ, SIP1 and Hoxc-8 [ 13 14 15 ] , and also its interaction with the master transcriptional co-activator CBP/p300 [ 16 ] . Smad4 is an essential functional partner in Smad-regulated transcription and also interacts with CBP/p300 via a domain within the central linker region named as SAD (Smad Activation Domain) [ 13 ] . Since CBP/p300 has intrinsic histone acetyltransferase (HAT) activity and participates in chromatin remodeling, the recruitment of CBP/p300 into the DNA-binding complexes of Smad1 and Smad4 is likely a critical step in Smad-regulated gene activation.
Instead of independently binding to specific DNA sequence to regulate transcription, Smads are now considered to be transcriptional modulators since their ability to regulate transcription is dependent, in most cases, on their physical interaction with other nearby DNA-binding transcription factors [ 11 ] . Thus, one of the fundamental questions in understanding Smad-regulated transcription is how Smads function as transcription modulators.
