24704453 results define the impact of alternative splicing on Fbx4 function, and suggest that the attenuated cyclin D1 degradation by these novel Fbx4 isoforms provides a new insight for aberrant cyclin D1 expression in human cancers.
24019069 The FBXO4 I377M mutant exhibits impaired cyclin D1 recruitment and ubiquitylation.
21242966 14-3-3varepsilon binds to Ser12-phosphorylated Fbx4 to mediate dimerization and function.
20181953 Biochemical studies indicate that both the N-terminal domain and a loop connecting the linker and C-terminal domain of Fbx4 are critical for the dimerization and activation of the protein.
20159592 results reveal an atypical small GTPase domain within Fbx4 as a substrate-binding motif for SCF(Fbx4) and uncover a mechanism for selective ubiquitination and degradation of TRF1 in telomere homeostasis control
18598945 Mutations in Fbx4 inhibit dimerization of the SCF(Fbx4) ligase and contribute to cyclin D1 overexpression in human cancer.
17081987 SCF(FBX4-alphaB crystallin) is an E3 ubiquitin ligase that promotes ubiquitin-dependent degradation of Thr286-phosphorylated cyclin D1.
16275645 Fbx4 is a central regulator of Pin2/TRF1 protein abundance and alterations in the stability of Pin2/TRF1 can have a dramatic impact on telomere length
