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 ] .
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.
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.
