This locus represents naturally occurring readthrough transcription between the neighboring RBM27 (RNA binding motif protein 27) and POU4F3 (POU domain, class 4, transcription factor 3) genes on chromosome 5. The readthrough transcript encodes a protein that shares sequence identity with the upstream gene product but its C-terminal region is distinct due to frameshifts relative to the downstream gene.
