Plexin B3 (PLXNB3)

Tamagnone et al. (1999) identified the cDNA sequence of a novel member of the plexin gene family, which they called plexin B3.Artigiani et al. (2004) showed that mammalian Plxnb3 is a high-affinity semaphorin-5A (SEMA5A) receptor. Plxnb3 was activated by Sema5a, and the Sema5a-Plxnb3 complex triggered intracellular signaling through Met, the receptor for hepatocyte growth factor.Tamagnone et al. (1999) found the PLXNB3 coding sequence in the genomic sequence of the ABCD1 gene on Xq28.Matsumoto et al. (2005) identified a partial deletion (exons 3 to 10) of the ABCD1 gene with fusion to the neighboring PLXNB3 gene. Sequencing showed that the breakpoints were at nucleotide +1374 in intron 2 of the ABCD1 gene and nucleotide +915 in intron 2 of the PLXNB3 gene.
