PLXNB3  Plexin-B3 is a protein that in humans is encoded by the "PLXNB3" gene. PLXNB3 has been shown to interact with ARHGEF11. Model organisms have been used in the study of PLXNB3 function. A conditional knockout mouse line called "Plxnb3tm1a(KOMP)Wtsi" was generated at the Wellcome Trust Sanger Institute. Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. Additional screens performed: - In-depth immunological phenotyping
