MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the PVR (poliovirus receptor) family of immunoglobin proteins. The product of this gene is expressed on several classes of T cells including follicular B helper T cells (TFH). The protein has been shown to bind PVR with high affinity; this binding is thought to assist interactions between TFH and dendritic cells to regulate T cell dependent B cell responses.[provided by RefSeq, Sep 2009]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit increased T cell proliferation, antigen presenting cell stimuation of T cell proliferation, and susceptibility to EAE. [provided by MGI curators]
