The most important regulatory control that restricts cyclins to the appropriate cell cycle stage is ubiquitin mediated, proteasome-dependent protein degradation. Which of the following statement is incorrect regarding to the degradation of protein?

#I Life Science/ Life Sciences Group – I-V

  1. SCF and APC/C are multisubunit ubiquitin-protein ligases that belong to the RING finger family of ubiquitin protein ligases which ensure that the cell cycle engine is driven forward and that cells cannot “go backward” in the cell cycle.

  2. SCF recognizes its substrates only when they are phosphorylated.

  3. The substrate specificity of active, dephosphorylated APC/C is determined in part by its association with one of two related substrate targeting factors called Cdc20 and Cdh1.

  4. The substrates of APC/C contain recognition motifs known as destruction box which is lysine rich.

Four different mutant lines showing similar phenotype were identified from a genetic screen. When genetic crosses among these mutants were carried out, the first mutant was found to complement the second, third and fourth mutant lines. However, no other complementation groups do the four mutant lines belongs to?
