UniProtKB accession:  Q9K0V0

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Neisseria acquires iron by extracting it from serum transferrin (TF) in its human host. Acts as a TF receptor and is required for TF utilization. Involved in the initial capture of TF. Helps select only those TF molecules that can be used as an iron source and concentrates them on the cell surface, maintaining the iron-loaded status of the TF C-terminal lobe until its delivery to TbpA.
