MRPS9 antisense RNA 2 (MRPS9-AS2)

MRPS9 antisense RNA 2 (MRPS9-AS2) is an antisense long non-coding RNA gene located on human chromosome 2, annotated primarily in locus-based gene databases including NCBI and Ensembl[1]. There is no evidence from current literature or gene databases that MRPS9-AS2 is a therapeutic target, has a defined biological function, or is involved in disease mechanisms. The primary protein-coding gene in this region, MRPS9 (Mitochondrial ribosomal protein S9), is distinct and encodes a protein involved in mitochondrial ribosome structure and function[3][7]. MRPS9 itself, but not MRPS9-AS2, is implicated in disease and therapeutic contexts, including cancer biomarker studies and mitochondrial physiology[2][3][4][7]. No structured information, validated aliases, molecular functions, disease roles, or drug interactions are indicated for MRPS9-AS2. This suggests either limited knowledge, a potential misspelling, or an incorrect identification as a target; MRPS9-AS2 is not considered a validated therapeutic target[1].
