Gene Information

human ... MS4A1(931)

General description

Cluster of differentiation 20 (CD20), also referred to as membrane spanning 4-domains A1 (MS4A1), is expressed on the surface of human B lymphocytes and on a small subset of T cells. The 33-35kDa, non-glycosylated protein has four membrane-spanning domains with both the amino and carboxy termini of the protein localized to the cytoplasm and a short 43 residue-extracellular segment. It is part of the membrane-spanning 4A gene family. The gene encoding MS4A1 is localized on human chromosome 11q12-13.

Application

The reagent is designed for Flow Cytometry analysis. Suggested working dilution for Flow Cytometry is 10 μg/mL of sample. Indicated dilution is recommended starting point for use of this product. Working concentrations should be determined by the investigator.

Biochem/physiol Actions

Cluster of differentiation 20 (CD20) participates in the development and cell cycle progression in B-cells. It has been found to interact with proteins like adapter protein p75/80, CD40 and major histocompatibility complex class II proteins (MHC II). It may participate in Ca2+ influx across plasma membranes, maintenance of Ca2+ concentration and activation of B-cells. CD20 activates Src leading to rapid phosphorylation of phospholipase C-γ1 (PLC-γ1) and PLC-γ2, in turn activating caspase-3 signaling of apoptosis. Overexpression of the gene has been associated with the development of primary cutaneous T-cell lymphomas (CTCL).
