SLC45A4 antisense RNA 2 (SLC45A4-AS2)

SLC45A4 antisense RNA 2 (SLC45A4-AS2) is a non-protein-coding antisense RNA transcript overlapping or adjacent to the SLC45A4 gene, which is itself a plasma membrane polyamine and sugar transporter implicated in neuronal pain signaling and tumor metabolism[1][3][5][6][7][9]. As a long non-coding RNA, SLC45A4-AS2 is presumed to modulate expression of SLC45A4 or neighboring genes through transcriptional interference, RNA-RNA interactions, or chromatin remodeling, consistent with established mechanisms for antisense lncRNAs[2][8][10]. Specific functional, clinical, or pharmacological roles of SLC45A4-AS2 are not characterized in the biomedical literature or major gene/protein databases as of September 2025[6].\nThe sense (protein-coding) transcript SLC45A4 is a well-characterized transporter protein with roles in pain and cancer, and serves as a therapeutic target in those contexts[1][3][5][7][9]. In contrast, SLC45A4-AS2's existence is documented (e.g., GeneCards), but its biological or therapeutic significance remains undetermined, so it is not classified as a canonical drug target, receptor, enzyme, transporter, or biomarker[6].
