Also known as RA-GEF-2PDZ-GEF2
Summary
RAPGEF6 (Rap guanine nucleotide exchange factor 6, HGNC:20655) is a protein-coding gene on chromosome 5q31.1, encoding Rap guanine nucleotide exchange factor 6 (Q8TEU7). Guanine nucleotide exchange factor (GEF) for Rap1A, Rap2A and M-Ras GTPases.
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.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 180 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
