General annotation (Comments)

Function

Mediates cellular binding of particles and immune complexes that have activated complement.

Subunit structure

Monomer.

Subcellular location

Membrane; Single-pass type I membrane protein.

Tissue specificity

Present on erythrocytes, leukocytes, glomerular podocytes, and splenic follicular dendritic cells.

Polymorphism

CR1 contains a system of antigens called the Knops blood group system. Polymorphisms within this system are involved in malarial rosetting, a process associated with cerebral malaria, the major cause of mortality in Plasmodium falciparum malaria. Common Knops system antigens include McCoy (McC) and Sl(a)/Vil (Kn4, or Swain-Langley; Vil or Villien). Sl(a-) phenotype is more common in persons of African descent and may protect against fatal malaria.

Miscellaneous

This is the sequence of the F allotype of CR1.

Sequence similarities

Belongs to the receptors of complement activation (RCA) family.

Contains 30 Sushi (CCP/SCR) domains.
