摘要: THE Polycomb group (Pc-G) genes are needed to maintain expression patterns of the homeotic selector Antennapedia (Antp-C) and bithorax (bx-C) complexes, hence for maintenance segmental determination1–3. We report predicted protein sequence Pc-G gene Posterior Sex Combs (Psc), neighbouring related Suppressor two zeste (Su(z)2). Both encode large proteins that contain a 200 amino-acid domain identical over 37.4% is also conserved in murine oncogene bmi-1 (refs 4,5). At amino terminus this cysteine-rich has been proposed as novel type zinc finger6.
