Genes affected

RBAK (HGNC:17680): (RB associated KRAB zinc finger) This gene encodes a nuclear protein which interacts with the tumor suppressor retinoblastoma 1. The two interacting proteins are thought to act as a transcriptional repressor for promoters which are activated by the E2F1 transcription factor. This protein contains a Kruppel-associated box (KRAB), which is a transcriptional repressor motif. Read-through transcripts that include exons from the downstream gene LOC389458 are expressed from this locus. [provided by RefSeq, Mar 2011]

RBAK links:

RBAK-RBAKDN (HGNC:42971): (RBAK-RBAKDN readthrough) This locus represents naturally occurring read-through transcription between the neighboring RBAK (RB-associated KRAB zinc finger) and LOC389458 (hypothetical LOC389458) genes on chromosome 7. The read-through 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.
