NCIt synonyms : Gene Regulated In Breast Cancer 1 Protein;
NCIt definition : Protein GREB1 (1949 aa, 216 kDa) is encoded by the human GREB1 gene. This protein
may be involved in estrogen-stimulated cell proliferation.;
NCIt note : There are at least four isoforms of protein GREB1 produced by alternative splicing.
The canonical isoform is GREB1a. GREB1b and GREB1c share 449 and 386 N-terminal amino
acids with GREB1a, respectively and have shorter, divergent C-terminal regions. The
fourth isoform is an N-terminally truncated form that is comprised of the 947 C-terminal
amino acids found in GREB1a. (UniProt and OMIM);
