The H1(FB1) antibody reacts with a cytoplasmic domain of CD20, a 33-37- kDa tetraspan phosphoprotein that is expressed on B lymphocytes from the pre-B stage and most malignant B cells and is lost during plasma cell differentiation. Low level CD20 expression is observed on a subset of normal circulating T lymphocytes, and CD20-positive T-cell lymphomas have been reported. The CD20 Molecule is associated with membrane lipid raft domains, acts as a channel for calcium ions, and is involved in regulation of B cell activation and survival. The cytoplasmic domain regions are serine and threonine rich and contain multiple phosphorylation consensus sequences.
