Function

This gene encodes a subunit of the heterotetrameric adaptor-related protein complex 1 (AP-1), which belongs to the adaptor complexes medium subunits family. This protein is capable of interacting with tyrosine-based sorting signals.[6]

Interactions

AP1M2 has been shown to interact with AP2B1.[7]
