Prostate cancer-associated transcript 6 (PCAT6), as a newly discovered carcinogenic long non-coding RNA (lncRNA), is abnormally expressed in multiple diseases. PCAT6 is also named KDM5B-AS1, KDM5BAS1, PCAN-R1, ncRNA-a2, or onco-lncRNA-96. It was first described as ncRNA-a2 in 2010. The gene of PCAT6 is located on chromosome 1q32.1 and contains two exons. It consists of 968 bp and has two transcript variants: transcript variant 1 (NR_046325.1) and transcript variant 2 (NR_046326.1).
