Revision as of 11:39, 2 January 2011
Ubiquitin (UBB) is found in almost all cells. It binds to proteins tagging them for destruction in the proteasome. UBB is activated by the UBB-activating enzymes E1, E2 and E3. UBB+1 is a frameshifted mutant of UBB observed in several diseases. A dimer of UBB (DiUBB) is formed by linkage of K48 to the C-terminus of a second UBB molecule. At least 4 UBB molecules are needed to tag a protein for the proteasome. The images at the left and at the right correspond to one representative Ubiquitin, i.e. the NMR structure of human Ubiquitin (1d3z).
