Entrez Gene summary for CR1 Gene:
This gene is a member of the receptors of complement activation (RCA) family and is located in the 'cluster RCA'
region of chromosome 1. The gene encodes a monomeric single-pass type I membrane glycoprotein found on
erythrocytes, leukocytes, glomerular podocytes, and splenic follicular dendritic cells. The Knops blood group
system is a system of antigens located on this protein. The protein mediates cellular binding to particles and
immune complexes that have activated complement. Decreases in expression of this protein and/or mutations in its
gene have been associated with gallbladder carcinomas, mesangiocapillary glomerulonephritis, systemic lupus
erythematosus and sarcoidosis. Mutations in this gene have also been associated with a reduction in Plasmodium
falciparum rosetting, conferring protection against severe malaria. Alternate allele-specific splice variants,
encoding different isoforms, have been characterized. Additional allele specific isoforms, including a secreted
form, have been described but have not been fully characterized. (provided by RefSeq, Jul 2008)

GeneCards Summary for CR1 Gene:
CR1 (complement component (3b/4b) receptor 1 (Knops blood group)) is a protein-coding gene. Diseases associated with CR1 include sarcoidosis, and diffuse glomerulonephritis. GO annotations related to this gene include complement component C3b binding and complement component C4b receptor activity. An important paralog of this gene is CSMD1.

UniProtKB/Swiss-Prot: CR1_HUMAN, P17927
Function: Mediates cellular binding of particles and immune complexes that have activated complement

    Polymorphic Variants from UniProtKB/Swiss-Prot
    CR1_HUMAN, P17927: 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
    CR1_HUMAN, P17927: Other polymorphic forms of CR1 contain 23, 37 or 44 Sushi (CCP/SCR) domains instead of the 30 Sushi
    (CCP/SCR) domains. The most frequent alleles are the F allotype (shown here) and the S allotype (37 repeat Sushi
    domains). The gene frequencies of the F allotype and S allotype are 0.87 and 0.11 in Caucasians, 0.82 and 0.11 in
    African Americans, 0.89 and 0.11 in Mexicans
    CR1_HUMAN, P17927: Genetic variations in CR1 resulting in CR1 deficiency are involved in protection against severe
    malaria [MIM:611162]. Parasitized red blood cells (RBCs) from children suffering from severe malaria often adhere
    to complement receptor 1 (CR1) on uninfected RBCs to form clumps of cells known as rosettes. CR1-deficient red
    blood cells show greatly reduced rosetting and CR1 deficiency occurs in healthy individuals from malaria-endemic
    regions
