Verification Images

Immunohistochemical analysis of paraffin-embedded mouse brain tissue using Transferrin Receptor 1 Antibody. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 8 minutes. The tissues were blocked in QuickBlock for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody at 1/100 dilution in 4℃ overnight. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX. -

Background
-
Function
Transferrin Receptor is a transmembrane glycoprotein. Transferrin Receptor consists of two isoforms, TfR1 and TfR2. Transferrin Receptor mediates the uptake of transferrin-iron complexes. Transferrin Receptor plays an important role in iron homeostasis as a gatekeeper regulating transferrin iron uptake. Transferrin Receptor is also considered as a proliferation marker and an attractive target for anticancer agents (e.g., a marker of poor prognosis in breast cancer) . Transferrin Receptor is associated with a variety of cancers including acute leukemia and breast cancer[1][2][3][4][5][6].

Subcellular Localization
Cell membrane; Single-pass type II membrane protein; Melanosome; Secreted
-
Expression
Induction:Regulated by cellular iron levels through binding of the iron regulatory proteins, IRP1 and IRP2, to iron-responsive elements in the 3'-UTR. Up-regulated upon mitogenic stimulation -
Subunit
Homodimer; disulfide-linked. Binds one transferrin or HFE molecule per subunit. Binds the HLA class II histocompatibility antigen, DR1. Interacts with SH3BP3. Interacts with STEAP3
