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 High affinity receptor for the Fc region of immunoglobulins gamma. Functions in both innate and adaptive immune responses. Mediates IgG effector functions on monocytes triggering antibody-dependent cellular cytotoxicity (ADCC) of virus-infected cells.SUBUNIT Interacts with the Fc region of IgG1, IgG2, IgG3 and IgG4 isotypes assembled in immune complexes (PubMed:11711607, PubMed:28566370, PubMed:25561553, PubMed:37421619). Interacts with FCERG1; forms a functional signaling complex. Interacts with FLNA; prevents FCGR1A degradation. Interacts with EPB41L2, LAT and PPL. Interacts with HCK and LYN.INTERACTION Stabilized at the cell membrane through interaction with FCER1G.ALTERNATIVE PRODUCTS Monocyte/macrophage specific.PTM Phosphorylated on serine residues.SIMILARITY Belongs to the immunoglobulin superfamily. FCGR1 family.ONLINE INFORMATION FCGR1A mutation db
