NCIt definition : Proto-oncogene DBL (925 aa, 108 kD) is encoded by the human MCF2 gene. This cytoplasmic
protein promotes the conversion of certain Rho GTPases from the GDP-bound form to
the GTP-bound form, thereby modulating their activity.;
NCIt note : The MCF2 gene encodes four isoforms of this protein, which have varying guanine nucleotide
exchange factor (GEF) activities toward the Rho GTPases CDC42, RAC1 and RHOA.;
