A number of them are thought to carry a distinctive five-residue motif termed the proteasome-interacting motif (PIM), which may have a biologically significant role in protein delivery to proteasomes and recruitment of proteasomes to transcription sites [5].

Three evolutionarily distinct families of SODs are known, of which the Mn/Fe-binding family is one. In humans, there is a cytoplasmic Cu/Zn SOD, and a mitochondrial Mn/Fe SOD. C-terminal domain is a mixed alpha/beta fold.

This protein anchors PKA for its role in regulating PKA-mediated gene transcription in both somatic cells and oocytes [1]. AKAP7_NLS carries the nuclear localisation signal (NLS) KKRKK, that indicates the cellular destiny of this anchor protein [2]. Binding to the regulatory subunits RI and RII of PKA is mediated via the family AKAP7_RIRII_bdg. at the C-terminus. This family represents a region that contains two 2'5' RNA ligase like domains Pfam:PF02834. Presumably this domain carried out some as yet unknown enzymatic function.
