RPL10A encodes ribosomal protein L10a, a component of the large (60S) ribosomal subunit essential for protein synthesis 123. Beyond its structural role in ribosomes, RPL10A exhibits specialized functions in development and disease. The protein is critical for mesoderm production during embryonic development, with Rpl10a loss-of-function in mice causing posterior trunk truncations and inhibiting paraxial mesoderm formation 4. Mechanistically, RPL10A-containing ribosomes preferentially translate specific mRNAs, including Wnt pathway components that regulate mesoderm differentiation 4. RPL10A expression is regulated by DKC1, which binds to and stabilizes RPL10A mRNA in colorectal cancer cells 5. Disease relevance includes significant upregulation in Alzheimer's disease brain capillaries alongside other ribosomal proteins, suggesting enhanced protein synthesis at the blood-brain barrier 6. Additionally, RPL10A shows altered binding patterns during SARS-CoV-2 infection, potentially influencing viral replication 7. Clinical significance extends to cardiac function, where Mendelian randomization analysis identified RPL10A as associated with cardiac structure and function traits 8. The protein is also found in exosomes from epicardial adipose tissue-derived stem cells under ischemic conditions, suggesting roles in cardiac regeneration 9.
