We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

| + | The hexameric AAA ATPase p97 is involved in several human proteinopathies and mediates ubiquitin-dependent protein degradation among other essential cellular processes. Via its N-terminal domain (N domain), p97 interacts with multiple regulatory cofactors including the UFD1/NPL4 heterodimer and members of the "ubiquitin regulatory X" (UBX) domain protein family; however, the principles governing cofactor selectivity remain to be deciphered. Our crystal structure of the FAS-associated factor 1 (FAF1)UBX domain in complex with the p97N domain reveals that the signature Phe-Pro-Arg motif known to be crucial for interactions of UBX domains with p97 adopts a cis-proline configuration, in contrast to a cis-trans mixture we derive for the isolated FAF1UBX domain. Biochemical studies confirm that binding critically depends on a proline at this position. Furthermore, we observe that the UBX proteins FAF1 and UBXD7 only bind to p97-UFD1/NPL4, but not free p97, thus demonstrating for the first time a hierarchy in p97-cofactor interactions. | ||
