RNA, 7SL, cytoplasmic 263, pseudogene (RN7SL263P)

Most human 7SL RNA sequences found in the genome are pseudogenes, dispersed copies that result from retrotransposition or other molecular mechanisms, and are generally truncated, nonfunctional fragments of the authentic SRP RNA gene[1]. RN7SL263P specifically designates one such locus, with no demonstrable transcriptional activity or biological function. Mislabeling it with aliases such as "breakpoint cluster region protein" (BCR) or linking it to the BCR protein is incorrect, as BCR is a distinct protein-coding gene—a kinase involved in intracellular signaling and oncogenic fusion proteins—that bears no relation to 7SL RNA pseudogenes[2][6]. Only the true 7SL RNA gene encodes the scaffold RNA of the signal recognition particle, essential for cotranslational membrane protein targeting[3][7]. Pseudogenes like RN7SL263P have no current utility as drug targets, disease biomarkers, or functional RNAs.
