Genes affected

RAPGEF6 (HGNC:20655): (Rap guanine nucleotide exchange factor 6) Enables several functions, including GTP-dependent protein binding activity; guanyl-nucleotide exchange factor activity; and phosphatidic acid binding activity. Involved in microvillus assembly; positive regulation of GTPase activity; and protein localization to plasma membrane. Located in several cellular components, including apical plasma membrane; centrosome; and endocytic vesicle. [provided by Alliance of Genome Resources, Apr 2022]
