Plexin-B3 is a protein that in humans is encoded by the PLXNB3 gene.^[1][2]

Interactions

PLXNB3 has been shown to interact with ARHGEF11.^[3][4]

Model organisms

Model organisms have been used in the study of PLXNB3 function. A conditional knockout mouse line called Plxnb3^{tm1a(KOMP)Wtsi} was generated at the Wellcome Trust Sanger Institute.^[5] Male and female animals underwent a standardized phenotypic screen^[6] to determine the effects of deletion.^{[7][8][9][10]} Additional screens performed: - In-depth immunological phenotyping^[11]
