SEPT5-GP1BB, Gene symbol SEPT5-GP1BB Gene description SEPT5-GP1BB readthrough See related Ensembl:ENSG00000284874 Gene type ncRNA RefSeq status VALIDATED Organism Homo sapiens Lineage Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo Also known as GP1BB; GPIbB; GPIb-beta Summary This locus represents naturally occurring read-through transcription between the neighboring SEPT5 (septin 5) and GP1BB (glycoprotein Ib (platelet), beta polypeptide) genes on chromosome 22. This read-through transcription arises from inefficient use of an imperfect polyA signal in the upstream SEPT5 gene, whereby transcription continues into the GP1BB gene. Alternative splicing results in multiple read-through variants. The read-through transcripts are candidates for nonsense-mediated mRNA decay (NMD), and are therefore unlikely to produce protein products.
