tetratricopeptide repeat protein
CDC27 family protein
Apc3, otherwise known as Cdc27, is one of the subunits of the anaphase-promoting complex or cyclosome. The anaphase-promoting complex is a multiprotein subunit E3 ubiquitin ligase complex that controls segregation of chromosomes and exit from mitosis in eukaryotes [1, 2]. The protein members of this family contain TPR repeats just as those of Apc7 do, and it appears that these TPR units bind the C-termini of the APC co-activators CDH1 and CDC20 [3]. [1]. 12049731.

tetratricopeptide repeat (TPR) protein may adopt a right-handed helical structure with an amphipathic channel and may function as an interaction scaffold in the formation of multi-protein complexes
