Example sentences for: mcaf
How can you use “mcaf” in a sentence? Here are some example sentences to help you improve your vocabulary:
Likewise, mCAF1, which has lost the N-terminal transactivation domain of yPOP2, binds to yCCR4 with a higher affinity than yPOP2 [ 11 ] .
This region can, by itself, activate transcription when targeted to the DNA via a heterologous DNA-binding domain [ 5 ] . On the other hand, the LRR plus C-terminal region of yCCR4 cannot mediate transcription activation, but is involved in protein-protein interactions [ 5 ] . The yCCR4 LRR is necessary for the binding of several components of the CCR4-NOT complex, including yPOP2 -and mCAF1- [ 11 ] , yDBF2 [ 2 ] , yCAF4 and yCAF16 [ 8 ] , and deletion of the yCCR4 N-terminus does not impair these associations.
Two homologs of yPOP2 have been identified in mammals: the mouse/human CAF1 [ 11 16 17 33 ] and, more recently, the human homolog named hPOP2 or hCALIF [ 18 19 ] . Both mCAF1 [ 11 ] and hPOP2 [ 19 ] interact with yCCR4, and the yCCR4 LRR is essential for these interactions.
Third, the ability of yCCR4 to bind mCAF1 and hPOP2 is conserved for the mammalian protein, since we could demonstrate, using two-hybrid assays and far-Western blot analyses, an in vivo and in vitro interaction between hCCR4 and hCAF1 or hPOP2/CALIF.
