Research progress of SMIM1 in Vel blood type, tumor and plasmodium infection / 中国输血杂志

ABSTRACT

Small integral membrane protein 1(SMIM1) gene encodes Vel blood group antigen, and homozygous deletion of 17 bases pairs in its exon 3 leads to Vel negative phenotype. As a rare phenotype, accurate identification and prevention of transfusion reaction for Vel negative phenotype is particularly important. In addition to serving as a Vel blood group antigen, recent bioinformatics analysis suggests that SMIM1 protein may be a new tumor biomarker involved in the occurrence and development of numerous tumors. Due to the similarity in structure between SMIM1 protein and glycoprotein, and its phosphorylation in red blood cells infected with Plasmodium falciparum, it is speculated that SMIM1 protein may be involved in the development of malaria. Therefore, this article provides a review of the related research on SMIM1 and its coding protein in Vel blood type, tumor and plasmodium infection.
