RPL7L1 (ribosomal protein L7 like 1) is a structural component of the cytosolic large ribosomal subunit involved in LSU-rRNA maturation from the tricistronic rRNA transcript. According to GO annotations, RPL7L1 functions in the mitochondrion and possesses both protein and RNA binding capabilities as a structural constituent of the ribosome. RPL7L1 has emerged as a potential biomarker in multiple disease contexts. In obesity research, RPL7L1 was identified as one of four robust obese-specific biomarkers in a comprehensive analysis of abdominal subcutaneous fat deposition, showing significant differential expression between obese and lean pigs and high diagnostic accuracy 1. Similarly, in lung adenocarcinoma pathogenesis, RPL7L1 was identified as a hub gene among mitochondrial and ribosomal proteins that are overexpressed and enriched in RNA processing, ribosome biogenesis, and mitochondrial translation—processes critical to LUAD progression 2. High expression of RPL7L1 in lung adenocarcinoma correlated with poor overall survival outcomes 2. RPL7L1 also appears relevant to ketamine anesthesia, where it was identified as a core gene in protein-protein interaction networks, though its specific mechanistic role requires further investigation 3. In molecular studies, RPL7L1 has been validated as a stable reference gene for RT-qPCR normalization in mouse skeletal muscle analysis 4, indicating its consistent expression under various conditions.
