LP14623-0   CD20
CD20 is a non-glycosylated phosphoprotein expressed on the surface of all mature B-cells.

Membrane-spanning 4-domains, subfamily A, member 1, also known as MS4A1, is a human gene.

This gene encodes a member of the membrane-spanning 4A gene family. Members of this nascent protein family are characterized by common structural features and similar intron/exon splice boundaries and display unique expression patterns among hematopoietic cells and nonlymphoid tissues. This gene encodes a B-lymphocyte surface molecule which plays a role in the development and differentiation of B-cells into plasma cells. This family member is localized to 11q12, among a cluster of family members. Alternative splicing of this gene results in two transcript variants which encode the same protein.
