CLSPN antisense RNA 1 (CLSPN-AS1)

CLSPN antisense RNA 1 (CLSPN-AS1) is a long non-coding antisense RNA transcribed opposite the CLSPN gene locus. While antisense RNAs can theoretically regulate expression of their sense gene via various mechanisms, there is currently no direct evidence describing the biological functions, disease associations, drug interactions, or clinical relevance of CLSPN-AS1. Nearly all available scientific and therapeutic data focus on the CLSPN gene and its encoded protein Claspin—a checkpoint mediator critical for DNA replication fidelity and cell cycle arrest following DNA damage[1][3][4][6]. Therefore, CLSPN-AS1 is not a recognized direct therapeutic target, and it is potentially an incorrect target designation for most clinical or research applications. For information related to DNA damage response, cell cycle checkpoint, and therapeutic targeting, consult references on CLSPN (Claspin) and its protein product. Key note: If your intention is to target the DNA damage checkpoint pathway, focus on CLSPN and its protein product (Claspin) rather than the antisense RNA[1][3][4][6].
