Summary

TEPSIN (TEPSIN adaptor related protein complex 4 accessory protein, HGNC:26458) is a protein-coding gene on chromosome 17q25.3, encoding AP-4 complex accessory subunit Tepsin (Q96N21). Associates with the adapter-like complex 4 (AP-4) and may therefore play a role in vesicular trafficking of proteins at the trans-Golgi network. It is a selective cancer dependency (DepMap: 10.0% of cell lines).

Located in coated vesicle membrane and trans-Golgi network membrane.

Function. Associates with the adapter-like complex 4 (AP-4) and may therefore play a role in vesicular trafficking of proteins at the trans-Golgi network.

Subunit / interactions. Interacts with AP4B1 and AP4E1; the interaction is direct and mediates the association of TEPSIN with the adapter-like complex 4 (AP-4), a heterotetramer composed of AP4B1, AP4E1, AP4M1 and AP4S1.
