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.

The mitochondrion-specific ribosomal protein mS41 family comprises proteins that are integral components of the mitochondrial ribosome, also known as the mitoribosome. These proteins play a crucial role in the dedicated translation machinery that synthesizes mitochondrial genome-encoded proteins, which include essential transmembrane subunits of the mitochondrial respiratory chain. The mitoribosomes are tethered to the mitochondrial inner membrane, ensuring that translation products are cotranslationally integrated into the membrane. Additionally, members of the mS41 family are implicated in the regulation of telomere length, a process essential for maintaining chromosome stability and cellular lifespan. Certain members are also required for survival upon exposure to specific environmental stressors, such as the K1 killer toxin.

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].
