Phosphatase Subfamily PPP5C

Phosphatase Classification: Fold MTDP: Superfamily MTDP: Family PPP: Subfamily PPP5C

Evolution

The PPP5C subfamily is found throughout eukaryotes, including opisthokonta, amoebazoa, plants and etc. PPP5Cs have tandem tetratricopeptide repeat (TPR) structural motifs at N-terminal, which distinguish them from other PPP subfamilies, and were used to find and classify PPP5C in yeast and dicty in phosphatome.net database.

Domain

The PPP5C subfamily has tandem tetratricopeptide repeat (TPR), a structural motif, at N-terminal and phosphatase domain at C-terminal.

Functions

PPP5C is the catalytic subunit of holoenzyme PP5, the function of which is reviewed at [1].
