A gene on Xq27 that encodes an oncogenic protein, a guanine nucleotide exchange factor (GEF) which controls some of the Rho family of small GTPases, promoting the conversion of some from the GDP-bound to the GTP-bound form. The MCF2 protein product is cleaved into MCF2-transforming protein and DBL-transforming protein.Segen's Medical Dictionary. © 2012 Farlex, Inc. All rights reserved.
