Entrez Gene Summary for ERMAP Gene

  • The protein encoded by this gene is a cell surface transmembrane protein that may act as an erythroid cell receptor, possibly as a mediator of cell adhesion. Polymorphisms in this gene are responsible for the Scianna/Radin blood group system. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

Variants for ERMAP Gene

Polymorphic Variants from UniProtKB/Swiss-Prot for ERMAP Gene

ERMAP is responsible for the Scianna/Radin blood group system which comprises seven different antigens. The Sc1 and Sc2 antigens are resulting from a single variation in position 57; Arg-57 corresponds to the Sc2 antigen and Gly-57 to the Sc1 antigen. The Sc2 antigen is rare with an occurrence of less than 1% in the population while Sc1 is more frequent. Sc3 is not expressed by individuals homozygous for a null allele encoding a truncated protein lacking its extracellular part (Sc-3). The Sc4 antigen corresponding to the previously defined Radin blood group antigen (Rd) is due to a single variation in position 60; Ala-60 corresponds to Sc4/Rd(+), the antigenic form of the protein. Sc4 is found in less than 1% of the population. Sc5/STAR, Sc6/SCER and Sc7/SCAN antigens are due to single variations in positions 47, 81 and 35 respectively. Alloantibodies to the low frequency Sc2 and Sc4 antigens are the cause of hemolytic disease in the newborn
