In molecular biology, HOXB13 antisense RNA 1 (non-protein coding), also known as HOXB13-AS1, is a long non-coding RNA. It was formerly known as PRAC2 (prostate, rectum, and colon 2). It was identified in a human prostate cDNA library, and (in humans) is found in the prostate, rectum, distal colon, and testis. In humans, it is found on chromosome 17q21.
