Summary
EXOC4 (exocyst complex component 4, HGNC:30389) is a protein-coding gene on chromosome 7q33, encoding Exocyst complex component 4 (Q96A65). Component of the exocyst complex involved in the docking of exocytic vesicles with fusion sites on the plasma membrane. It is a selective cancer dependency (DepMap: 31.5% of cell lines).
The protein encoded by this gene is a component of the exocyst complex, a multiple protein complex essential for targeting exocytic vesicles to specific docking sites on the plasma membrane. Though best characterized in yeast, the component proteins and functions of exocyst complex have been demonstrated to be highly conserved in higher eukaryotes. At least eight components of the exocyst complex, including this protein, are found to interact with the actin cytoskeletal remodeling and vesicle transport machinery. The complex is also essential for the biogenesis of epithelial cell surface polarity. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 190 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.
