E3 ubiquitin-protein transferase MAEA (MAEA)

Plays a role in erythroblast enucleation and in the creation of the mature macrophages. Mediates the attachment of erythroid cell to mature macrophages, in correlation with the presence of MAEA at cell surface of mature macrophages; This MAEA- mediated contact inhibits erythroid cells apoptosis.

Participates in erythroblastic island creation, that is the practical unit of definitive erythropoiesis. Associates with F-actin to regulate actin distribution in erythroblasts and macrophages.
