Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Subunit of clathrin-associated adaptor protein complex 1 that plays a role in protein sorting in the trans-Golgi network (TGN) and endosomes. The AP complexes mediate the recruitment of clathrin to membranes and the recognition of sorting signals within the cytosolic tails of transmembrane cargo molecules.SUBUNIT Adaptor protein complex 1 (AP-1) is a heterotetramer composed of two large adaptins (gamma-type subunit AP1G1 and beta-type subunit AP1B1), a medium adaptin (mu-type subunit AP1M1 or AP1M2) and a small adaptin (sigma-type subunit AP1S1 or AP1S2 or AP1S3). Interacts with MARCHF11 (By similarity). Associates with the AP1(MU)-Nef-MHC-I complex; this complex is required for MHC-I internalization.SUBUNIT (Microbial infection) Interacts with HIV-1 Nef.INTERACTION Component of the coat surrounding the cytoplasmic face of coated vesicles located at the Golgi complex.ALTERNATIVE PRODUCTS Phosphorylation of membrane-bound AP1M1/AP1M2 increases its affinity for sorting signals.SIMILARITY Belongs to the adaptor complexes medium subunit family.
