tetratricopeptide repeat protein
This family is found predominantly at the C-terminus of transglutaminase enzyme core regions. (from Pfam)
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.

Protein prenyltransferase alpha subunit repeat
Both farnesyltransferase (FT) and geranylgeranyltransferase 1 (GGT1) recognise a CaaX motif on their substrates where 'a' stands for preferably aliphatic residues, whereas GGT2 recognises a completely different motif. Important substrates for FT include, amongst others, many members of the Ras superfamily. GGT1 substrates include some of the other small GTPases and GGT2 substrates include the Rab family [2].
