Neurodevelopmental disorder mutations in the exchange factor DENN/MADD disrupt activation of Rab GTPases.

Abstract excerpt

DENN/MADD (mitogen-activated protein kinase-activating death domain), a differentially expressed in normal and neoplastic cells (DENN) domain-containing protein functions in membrane trafficking. DENN domain-bearing proteins have guanine nucleotide exchange factor activity toward Rab GTPases. Here, we identify Rab GTPase substrates for DENN/MADD using a cell-based assay involving DENN domain-mediated recruitment...
