K11-linked polyubiquitination in cell cycle control revealed by a K11 linkage-specific antibody.
Polyubiquitination is a posttranslational modification where ubiquitin chains containing isopeptide bonds linking one of seven ubiquitin lysines with the C terminus of an adjoining ubiquitin are covalently attached to proteins. While functions of K48- and K63-linked polyubiquitin are understood, the role(s) of noncanonical K11-linked chains is less clear. A crystal structure of K11-linked diubi...
متن کاملc-IAP1 and UbcH5 promote K11-linked polyubiquitination of RIP1 in TNF signalling.
Ubiquitin ligases are critical components of the ubiquitination process that determine substrate specificity and, in collaboration with E2 ubiquitin-conjugating enzymes, regulate the nature of polyubiquitin chains assembled on their substrates. Cellular inhibitor of apoptosis (c-IAP1 and c-IAP2) proteins are recruited to TNFR1-associated signalling complexes where they regulate receptor-stimula...
متن کاملc-IAP1 and UbcH5 promote K11-linked polyubiquitination of RIP1 in TNF signaling
Thank you again for submitting your manuscript for consideration by The EMBO Journal. It has now been seen by three expert reviewers, whose comments are copied below. As you will see, they all consider your results as a first implication of K11-linked ubiquitin chains in TNF signaling interesting and potentially important and thus in principle suited for publication in The EMBO Journal. Neverth...
متن کاملK11-linked ubiquitin chains as novel regulators of cell division.
Modification of proteins with ubiquitin chains is an essential regulatory event in cell cycle control. Differences in the connectivity of ubiquitin chains are believed to result in distinct functional consequences for the modified proteins. Among eight possible homogenous chain types, canonical Lys48-linked ubiquitin chains have long been recognized to drive the proteasomal degradation of cell ...
متن کاملIdentification of bacteriophage K11 genomic promoters for K11 RNA polymerase.
Only one natural promoter that interacts with bacteriophage K11 RNA polymerase has so far been identified. To identify more, in the present study restriction fragments of the phage genome were individually assayed for transcription activity in vitro. The K11 genome was digested with two 4-bp-recognizing restriction enzymes, and the fragments cloned in pUC119 were assayed with purified K11 RNA p...
