Background
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],
Function
developmental stage:Expressed in fetal liver blood cells (at protein level). Highly expressed in fetal liver.,function:Possible role as a cell-adhesion or receptor molecule of erythroid cells.,online information:Blood group antigen gene mutation database,polymorphism: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 cor
