Alpha 250/ Alpha 280
Two overlapping antisense RNAs from intron 1 of the human ribosomal protein 14 (Rps14) gene, identified by RNase Protection Assay (RPA).. RPA expression analysis using both cell extracts and cell-free transcription system indicates full-length sizes of 250 and 280 nt, respectively. Transcripts terminate at the same nucleotide, therefore alpha-250 overlaps alpha-280 along its whole length.. Transcription of both RNAs is resistant to high concentrations of RNAPII inhibitor alpha-amanitin.
Regulates RPS14 transcription.. Each lncRNA can interact with the Rps14 gene loci to stimulate its expression in-trans.. Each lncRNA is transcribed through a known enhancer with putative transcription factor binding abilities, suggesting the 'enhancer' may be the transcribed RNA, which could be recruiting transcription factors to the Rps14 gene.
Ubiquitously expressed in the human tissues and cell lines examined. . Alpha-250 was almost exclusively cytoplasmic. Alpha- 280 was mostly in the nucleus.
