In molecular biology the adaptor complexes medium subunit domain is a protein domain found at the C-terminus of the mu subunit from various clathrin adaptors (AP1 AP2 and AP3). The C-terminal domain has an immunoglobulin-like beta-sandwich fold consisting of 9 strands in 2 sheets with a Greek key topology similar to that found in cytochrome f and certain transcription factors.
