title: Transcription elongation factor SII (TCEA) maps to human chromosome 3p22 --> p21.3.
abstract: Transcription elongation factors assist RNA polymerase II through transcriptional blockages. The human transcriptional elongation factor SII or Trascription Elongation Factor A (TCEA) releases RNA polymerase II from transcriptional arrest and is encoded by a 2.5-kb intronless gene. Using PCR primers, verified by RT-PCR to amplify the authentic, transcriptionally active SII gene, this locus was mapped to human chromosome 3 by examination of a human/rodent somatic cell hybrid panel. PCR analysis of somatic cell hybrids with chromosome 3 translocations and FISH studies utilizing a human YAC clone containing the SII gene further refine the map position of this locus to human chromosome 3p22 --> p21.3. Since another elongation factor, SIII, has been implicated in human carcinogenesis and since the interval within which the human SII gene maps is frequently deleted in certain cancers, elongation factor SII may therefore be considered a candidate gene for human malignancies involving 3p22 --> p21.3.
