Summary

AURKAIP1 (aurora kinase A interacting protein 1, HGNC:24114) is a protein-coding gene on chromosome 1p36.33, encoding Small ribosomal subunit protein bS22, mitochondrial (Q9NWT8). May act as a negative regulator of Aurora-A kinase, by down-regulation through proteasome-dependent degradation. It is a selective cancer dependency (DepMap: 35.3% of cell lines).

Acts upstream of or within positive regulation of proteolysis. Located in mitochondrial matrix and nucleoplasm.

All UniProt accessions (1): Q9NWT8

Function. May act as a negative regulator of Aurora-A kinase, by down-regulation through proteasome-dependent degradation.

Subunit / interactions. Component of the mitochondrial small ribosomal subunit (mt-SSU). Mature mammalian 55S mitochondrial ribosomes consist of a small (28S) and a large (39S) subunit. The 28S small subunit contains a 12S ribosomal RNA (12S mt-rRNA) and 30 different proteins. The 39S large subunit contains a 16S rRNA (16S mt-rRNA), a copy of mitochondrial valine transfer RNA (mt-tRNA(Val)), which plays an integral structural role, and 52 different proteins. Interacts with Aurora-A.

Subcellular location. Mitochondrion matrix. Nucleus.

Tissue specificity. Ubiquitously expressed and especially highly expressed in heart, skeletal muscle and testis.

Miscellaneous. Initially thought to be mitochondrial specific, comparison with ribosomes from Actinomycetota shows this protein is also found in some bacteria. Thus it has been renamed.

Similarity. Belongs to the bacterial ribosomal protein bS22 family.
