A STKR member that binds to TGFβ (Transforming growth factor) is a membrane receptor that can be divided into two subclasses (Type I and Type II).
This histidine arrangement is conserved in α- and γ-subclass type-3 copper proteins, whilst β-subclass type-3 copper proteins exhibit a different position of the second histidine residue in the Cu(A -binding site.
In arthropods, duplication of β-subclass type-3 copper proteins gave rise to contemporary arthropod hemocyanin and tyrosinase proteins.
This ancestral gene duplicated and diverged prior to the split of unikont eukaryote lineages, giving rise to a cytoplasmic β-subclass type-3 copper protein.
As the membrane-bound γ form is present only in metazoan genomes (no type-3 copper proteins were detected in the holozoans Monosiga brevicolis and Capsaspora owczarzaki) and is more closely related to α-subclass type-3 copper proteins, we infer that the γ-subclass arose from a second duplication of an α-subclass type-3 copper protein gene.
For example, α-subclass type-3 copper protein in plants (G. max, 12 genes), chromalveolates (E. siliculosus, 18 genes) and nematodes (C. elegans, 5 genes; C. briggsae, 6 genes; C. remanei, 5 genes and B. malayi, 4 genes) have undergone large gene expansions, whilst β- and γ- subclasses have expanded significantly in arthropods (A. gambiae, 9 genes) and cephalochordates (B. floridae, 18 genes).
It has been placed into a subclass of type II restriction and modification enzymes - type IIC.

Kappa Pavonis is a W Virginis variable a subclass of Type II Cepheid.
A subclass of Type IIG RM systems consists of a similar S subunit and a polypeptide carrying both modification and restriction activities (Fig. 1B) [1B].
