Genes affected

RAP2A (HGNC:9861): (RAP2A, member of RAS oncogene family) Enables GTPase activity; guanyl ribonucleotide binding activity; and magnesium ion binding activity. Involved in several processes, including actin cytoskeleton reorganization; microvillus assembly; and positive regulation of protein autophosphorylation. Acts upstream of or within establishment of protein localization. Located in plasma membrane and recycling endosome membrane. [provided by Alliance of Genome Resources, Apr 2022]
