Melanotransferrin (CD228)

Target
CD228
Molecular classification
Transferrin superfamily, Glycoprotein
01

Overview

Melanotransferrin (CD228) is a member of the transferrin superfamily, characterized as a heavily glycosylated, GPI-anchored membrane protein. It binds a single ferric iron atom and is highly expressed in melanoma and other cancers, as well as fetal tissues. It is involved in iron homeostasis, tumor progression, and regulation of cell differentiation, making it a therapeutic target for antibody-drug conjugates.
