Skp/Cullin/F-box (SCF) complexes are part of a large family of E3 ubiquitin ligases in which F-box proteins determine substrate specificity.
Substrate selection by F-box proteins may also be aided by accessory cofactors.
The F-box only protein 4, FBX4, interacts via its F-box with SKP1 and CUL1 to form SCFFBX4 ubiquitin ligase.
The activity of the SCFFBX4 complex can be regulated by aB crystallin, a small heat shock protein which serves as a specificity cofactor for FBX4 dependent ubiquitination.
FBX4 together with aB crystallin (SCFFBX4-aB crystallin) promotes the ubiquitination of cyclin D1 phosphorylated at 286aa.
In addition, the SCFFBX4-aB crystallin ubiquitin ligase has been implicated in the ubiquitination of unknown substrates in desmin-related myopathy.
SCFFBX4, in the absence of aB crystallin, also ubiquitinates the telomeric protein PIN2/TRF1.
