40S ribosomal protein S10
Function
Component of the 40S ribosomal subunit (PubMed:23636399). The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell (PubMed:23636399).
Involvement in disease
Diamond-Blackfan anemia 9
DBA9
A form of Diamond-Blackfan anemia, a congenital non-regenerative hypoplastic anemia that usually presents early in infancy. Diamond-Blackfan anemia is characterized by a moderate to severe macrocytic anemia, erythroblastopenia, and an increased risk of malignancy. 30 to 40% of Diamond-Blackfan anemia patients present with short stature and congenital anomalies, the most frequent being craniofacial (Pierre-Robin syndrome and cleft palate), thumb and urogenital anomalies.
None
The disease is caused by variants affecting the gene represented in this entry.
Post-translational modifications
Methylated by PRMT5. Methylation is necessary for its interaction with NPS1, its localization in the granular component (GC) region of the nucleolus, for the proper assembly of ribosomes, protein synthesis and optimal cell proliferation.
Monoubiquitinated by ZNF598 when a ribosome has stalled during translation of poly(A) sequences, leading to preclude synthesis of a long poly-lysine tail and initiate the ribosome quality control (RQC) pathway to degrade the potentially detrimental aberrant nascent polypeptide (PubMed:28065601, PubMed:28132843, PubMed:28685749, PubMed:32011234, PubMed:36302773). Deubiquitinated by OTUD3 and USP21, antagonizing ZNF598 activity (PubMed:32011234). Deubiquitinated by OTUD1, antagonizing ZNF598 activity and stimulating formation of polysomes: deubiquitination by OTUD1 promotes stability and translation of a subset mRNAs with a high abundance of rare codons can limit the translation rate (PubMed:36445135). Deubiquitinated by USP10 (PubMed:31981475).
Sequence Similarities
Belongs to the eukaryotic ribosomal protein eS10 family.
