Semaphorin 4D/CD100 Antibody (SEMA4D/933) Summary

• Immunogen: Human recombinant Semaphorin 4D/CD100 protein
• Localization: Cell surface
• Specificity: Recognizes a homodimeric protein comprised of 50kDa subunits, identified as CD100. It is expressed on majority of haemopoietic cells (B, T, NK and myeloid cells) and is absent from bone marrow, erythrocytes, eosinophils and endothelial cells. Its expression is increased after PHA-activation. CD100 was shown to associate with different partner molecules in T cells such as CD45, a key molecule with protein tyrosine phosphatase activity involved in T-cell transduction, and a Serine kinase. It plays a role in homotypic cell adhesion and in T cell activation.

Background

Semaphorins are neuronal chemorepellants that direct pioneering neurons during nervous system development. CD100, a 150 kDa homodimer, is a novel semaphorin that induces B cells to aggregate and improves their viability in vitro. CD100 modifies CD40-CD40L B cell signaling by augmenting B cell aggregation and survival and down regulating CD23 expression. CD72 is a lymphocyte receptor for the class IV semaphorin CD100, which is involved in regulating B cell signaling. CD100 is expressed on resting and PHA stimulated T cells. The protein is weakly expressed on NK cells, EBV transformed B cells, monocytes and tumor/peripheral blood T cell lines, and at higher density on activated T cells and B cells.
