FIG. 2.

Alignment of CRV and cellular F-box proteins. The highlighted, boldface, and capital letters indicate residues similar to a previously described 234 F-box consensus (65). Residues in boldface type are present in >40% of this previously described data set, those highlighted are present in 20 to 40%, and those in capital letters are present in greater than 10%. Amino acid positions are indicated on the right. F-box protein sequence names correspond to the following GenBank accession numbers: rat, Q7TSL3; mouse, Q9QZM8; and human, Q96EF6.
