NRPB7 — Glycine max

Summary

GLYMA_05G130300V4 (symbol NRPB7, preferred name GmNRPB7) on soybean chromosome 5 encodes a protein with an Rpb7-like N-terminal domain and an S1 domain, and is annotated with translation initiation factor binding, nucleic acid binding, and single-stranded DNA and RNA binding activities. The gene is associated with the RNA polymerase II core complex, nucleus, and P-body localisation, and is linked to biological processes including transcription initiation from Pol II promoters, positive regulation of nuclear-transcribed mRNA poly(A) tail shortening, DNA amplification, regulation of photosynthesis, nitrogen fixation, endosperm development, and response to short-day conditions. Associations with agronomic traits include soluble protein content, nitrogen content, protein content, germination rate, and salt tolerance. Related genes in other species link the family to DNA-directed RNA polymerase subunit function.
