name: nuclear factor NF-kappa-B p50 subunit
def: "A nuclear factor NF-kappa-B p105 subunit isoform 1 that has been processed by proteolytic cleavage to remove the C-terminal domain of p105 downstream from the 23-residue glycine rich region (GRR). Example: UniProtKB:P19838-1, 1-433." [PRO:DAN, PRO:JAN, PMID:2203532, PMID:8628291]
comment: Category=modification. Note: GRR functions as a processing signal for the generation of the p50 subunit.
