MRPS26 (mitochondrial ribosomal protein S26) is a component of the mitochondrial small ribosomal subunit involved in mitochondrial translation 1. As a mitochondrial ribosomal protein, MRPS26 functions in RNA binding and localizes to the mitochondrial inner membrane where it participates in protein synthesis within mitochondria. Mechanistically, MRPS26 is part of the mitochondrial translation machinery essential for synthesizing proteins encoded by mitochondrial DNA. Dysregulation of MRPS26 expression has been identified as a biomarker in multiple disease contexts. In childhood allergic asthma (CAS), MRPS26 was identified as a hub gene among mitochondria-related biomarkers, with downregulated expression in CAS samples 1. The study suggested that altered MRPS26 expression may influence inflammatory responses by affecting mitochondria-related functions. In non-small cell lung cancer (NSCLC), dysregulated MRPS26 expression was linked to reduced survival and tumor purity, with an inverse expression pattern compared to healthy older adults 2. Additionally, MRPS26 was identified among core genes associated with ischemic stroke pathology 3. These findings suggest MRPS26 dysregulation may contribute to mitochondrial dysfunction across diverse disease states, though the specific mechanistic roles require further investigation.
