Description

Semaphorin-4A/SEMA4A is the cell surface receptor for PLXNB1, PLXNB2, PLXNB3, and PLXND1 and is essential for intercellular signaling. It induces TIMD2 phosphorylation, inhibits angiogenesis, and collapses axonal growth cones.

Background

Semaphorin-4A (SEMA4A) serves as a cell surface receptor for PLXNB1, PLXNB2, PLXNB3, and PLXND1, playing a pivotal role in cell-cell signaling. This multifaceted protein is implicated in the regulation of glutamatergic and GABAergic synapse development, fostering inhibitory synapses in a PLXNB1-dependent manner and excitatory synapses in a PLXNB2-dependent manner. Additionally, SEMA4A contributes to adaptive immunity by priming antigen-specific T-cells, promoting the differentiation of Th1 T-helper cells, and facilitating the phosphorylation of TIMD2. Furthermore, SEMA4A exerts inhibitory effects on angiogenesis, induces axon growth cone collapse, and hinders axonal extension by providing localized signals that specify territories inaccessible for growing axons. Its intricate role is underscored by interactions with PLXNB1, PLXNB2, PLXNB3, PLXND1, and TIMD2, emphasizing its involvement in diverse cellular processes.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
