  ABSTRACT  
 
Posttranslational modification of proteins with polyubiquitin occurs in diverse signaling pathways and is tightly regulated to ensure cellular homeostasis. Studies employing ubiquitin mutants suggest that the fate of polyubiquitinated proteins is determined by which lysine within ubiquitin is linked to the C terminus of an adjacent ubiquitin. We have developed linkage-specific antibodies that recognize polyubiquitin chains joined through lysine 63 (K63) or 48 (K48). A cocrystal structure of an anti-K63 linkage Fab bound to K63-linked diubiquitin provides insight into the molecular basis for specificity. We use these antibodies to demonstrate that RIP1, which is essential for tumor necrosis factor-induced NF-kappaB activation, and IRAK1, which participates in signaling by interleukin-1beta and Toll-like receptors, both undergo polyubiquitin editing in stimulated cells. Both kinase adaptors initially acquire K63-linked polyubiquitin, while at later times K48-linked polyubiquitin targets them for proteasomal degradation. Polyubiquitin editing may therefore be a general mechanism for attenuating innate immune signaling.

Figure 1. Structural Analysis of Apu2.16 and Apu3.A8 Anti-K63 Linkage Fabs Bound to K63-Linked Diubiquitin
(A) The complex between K63-linked diubiquitin (orange) and the Apu2.16 Fab fragment (heavy chain: green, light chain: magenta). Heavy chain CDR3 (H3) contacts both ubiquitins on either side of the isopeptide linkage. H3 side chains within 4.2 Å of diubiquitin and ubiquitin side chains within 4.2 Å of H3 are shown as sticks. Residues mentioned in the text are in bold for ubiquitin and italics for the Fab. K63 in the acceptor ubiquitin is shown as a sphere.
(B) Comparison of K63- (top) and K48-linked (bottom) diubiquitin. Lysine donor ubiquitins are light orange and acceptor ubiquitins are bright orange. K48-linked diubiquitin forms a more compact shape with the chain extending perpendicular to the ubiquitin dimer, while the K63-linked diubiquitin chain will extend in a more elongated manner.
(C) Superposition of Apu2.16 (colored as in A) and Apu3.A8 (heavy chain: light green, light chain: pink) showing the location of the two changes in L2 (S52R) and H3 (S52T) introduced in the affinity maturation process to create Apu3.A8. The structural differences in L1 in the two Fabs are likely due to crystal packing. L1 (as well as the N terminus) are in a noncanonical conformation likely due to interactions with L3, which has sequence and structural differences relative to the phage library parent sequence (Figure S2).
(D) Charge complementarity between Apu3.A8 (transparent) and diubiquitin (solid). Electrostatic surfaces were calculated with PyMol. Regions of positive potential are blue; regions with negative potential are red. In the Apu3.A8 light chain, R52 (which is introduced in Apu3.A8) and R66 contribute to a positive region that is close to a negatively charged region on the ubiquitin surface, created in part by residues D21, D58, and E18 from the K63 acceptor ubiquitin.

Figure 3. Mass Spectrometry Confirms the Linkage Specificity of Apu2.07 and Apu3.A8 in Immunoprecipitations
(A–D) BJAB cell lysates were immunoprecipitated with Apu2.07, Apu3.A8, or an isotype control antibody recognizing HER2. Mass spectrometry was used to determine the total amount of ubiquitin immunoprecipitated (A) as well as the polyubiquitin linkages in the lysate (B) and immunoprecipitates (C and D).
(E) MuRF1 autoubiquitination reactions performed in vitro with WT, K48R, or K63R ubiquitin were immunoprecipitated with Apu2.07, Apu3.A8, or isotype control. Numbers in parentheses indicate the relevant lanes and columns in (F)–(I).
(F) Autoubiquitination reactions and immunoprecipitations depicted in (E) were western blotted with a pan-ubiquitin antibody. The hatched red lines indicate the portion of the gel that was cut out and subjected to analysis by mass spectrometry.
(G–I) Mass spectrometry was used to determine the polyubiquitin linkages in the autoubiquitination reactions and immunoprecipitations depicted in (E).

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
