Example sentences for: hcaf
How can you use “hcaf” in a sentence? Here are some example sentences to help you improve your vocabulary:
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.
Here we report the identification of nineteen yCCR4-like proteins in eukaryotes and show, by phylogenetic and genomic analyses, that they are grouped into four distinct families, one of which contains the yCCR4 orthologs : these orthologs, in animals, have conserved the yCCR4 leucine-rich repeat, and we show, using two-hybrid assays and far-Western experiments, that the human protein binds to the human yPOP2 homologs, i.e. hCAF1 and hPOP2, in a LRR-dependent manner.
Indeed, both human homologs of yPOP2, hCAF1 and hPOP2, lack the 148 N-terminal amino acids which are, in yPOP2, required for transcriptional activation, whereas the yPOP2 C-terminus, which is involved in the interaction with yCCR4, is conserved in hCAF1 [ 11 ] and hPOP2 [ 19 ] . Similarly, hNOT2, the human homolog of the yNOT2 component of the CCR4-NOT complex, harbors a N-terminal domain divergent from that of yNOT2 -required for transcriptional activation and interaction with the yeast ADA2 factor-, but has conserved the C-terminal domain which is absolutely required for the yCCR4-associated function of yNOT2 [ 19 20 ] . Therefore, it looks as if genes of the CCR4-NOT complex have undergone a "concerted" phylogenetic evolution, with the yeast genes encoding multifunctional proteins and the animal genes only encoding "specialized" proteins specific for the CCR4-NOT complex.
Interaction of the human homolog of yCCR4 with hCAF1 and hPOP2/CALIF
4B, co-expression of pGal4-hCCR4 with either pVP16-hCAF1 or pVP16-hPOP2 elicited a significant increase (> 35 fold) in pG4-TK-Luc expression, thus demonstrating association between hCCR4 and either hCAF1 or hPOP2.
