'''Haptoglobin receptor''' (IsdH) is part of the iron-regulated surface determinant system that captures heme from the host hemoproteins. IsdH binds haptoglobin (Hp) which removes hemoglobin (Hb) from the blood by forming Hp-Hb complex. IsdH contains multiple '''NEAT''' (Near Transporter) domains which bind proteins and heme<ref>PMID:18451305</ref>.
