Target Background

Function(From Uniprot)
This protein is a minor sialoglycoprotein in erythrocyte membranes.
Gene References into Functions
  1. through bioinformatic analysis, identified extensive variation in GYPB transcript levels in individuals from Benin, suggesting selection from malaria pressure; collective data suggest that the GPA and GPB receptors are of greater importance than the GPC receptor, supporting a hierarchy of erythrocyte receptor usage in P. falciparum PMID:28760933
  2. A novel GYPB mutation (c.270+5G>A) accounting for the S-s-U+(var) phenotype was identified. PMID:24738877
  3. Substitution of GPB with Gp.Mur significantly reduced the expression of Rh antigen and RhAG on the Mi.III(+/+) erythrocyte membrane PMID:21883272
  4. an increased susceptibility to infection by this parasite is associated with the glycophorin B S+ variant in Brazilian Amazons PMID:21283638
  5. Indochina I strain of P. falciparum is not dependent on glycophorin B to invade erythrocytse through a trypsin-resistant pathway as are the strains 3D7, HB3, and Dd2. PMID:14638759
  6. The S-s-U+var phenotype arises from changes in or around GYPB exon 5. PMID:14641872
  7. Alternative to conventional tube technique for mass screening for MNS hybrids, especially when specific antisera are not available. PMID:17561857
  8. Immunoblotting showed the presence of monomer and dimer forms of a GP(A-B) hybrid and an absence of GPA and GPB. Sequencing of DNA and PCR-RFLP using the restriction enzyme RsaI confirmed the presence of a hybrid GYP(AB). PMID:18284304
  9. The erythrocyte-binding domain, region 2 of EBL-1, bound glycophorin B(+) but PMID:19279206
  10. This study reports for the first time the molecular mechanisms responsible for the S-s- phenotype in a population of African Brazilians and provides new information about the frequency and molecular bases of the GYPB*S silent gene in this population. PMID:19856717
