Conserved Site

Clathrin adaptor, mu subunit, conserved site (IPR018240)

Short name: Clathrin_mu_CS


This entry represents the mu subunit of various clathrin adaptors (AP1, AP2 and AP3) [PMID: 11583591]. The mu subunit regulates the coupling of clathrin lattices with particular membrane proteins by self-phosphorylation via a mechanism that is still unclear [PMID: 1761056]. The mu subunit possesses a highly conserved N-terminal domain of around 230 amino acids, which may be the region of interaction with other AP proteins; a linker region of between 10 and 42 amino acids; and a less well-conserved C-terminal domain of around 190 amino acids, which may be the site of specific interaction with the protein being transported in the vesicle [PMID: 1761056].
