RPB2 — Beta vulgaris subsp. vulgaris

Summary

BVRB_028820 (symbol RPB2) on sugar beet chromosome 114418 encodes a DNA-directed RNA polymerase with RNA polymerase II core complex protrusion domain, possessing DNA-directed RNA polymerase activity (EC 2.7.7.6), ribonucleoside and DNA binding, and zinc binding. The gene is associated with DNA-templated transcription elongation, transcription initiation from Pol II promoter, RNA-dependent gene silencing, translation elongation, NO storage, and DNA-dependent transcription. The encoded product localises to the DNA-directed RNA polymerase complex and RNA polymerase II core complex. Related genes in other species link the family to transcription elongation and Pol II promoter initiation.
