Official Name
MS4A1
Full Name
membrane spanning 4-domains A1
Background
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.

Involvement in Disease
Its related pathways are Hematopoietic cell lineage and Hematopoietic Stem Cells and Lineage-specific Markers.
Related Pathways
b lymphocyte-specific membrane protein, which is involved in the regulation of cellular calcium influx necessary for the development, differentiation and activation of b lymphocytes (PubMed:3925015, PubMed:7684739, PubMed:12920111). After activation of b-cell receptor/BCR, it acts as a component of stored and operated calcium (SOC) channels to promote calcium influx (PubMed:7684739, PubMed:12920111, PubMed:18474602).

Description
Ofatumumab's first human monoclonal antibody targeting the CD20 molecule was approved by the FDA in 2014 for the treatment of refractory chronic lymphocytic leukemia. It appears to inhibit the activation of early B lymphocytes, showing potential for treating follicular lymphoma, diffuse large B-cell lymphoma, rheumatoid arthritis and relapsing multiple sclerosis. This antibody can be used in patients with refractory CLL.

Chronic lymphocytic leukaemia
Phase IIIB-cell lymphoma
Diffuse large B cell lymphoma
Follicular lymphoma
Multiple sclerosis
Phase II Marginal zone B-cell lymphoma
Precursor cell lymphoblastic leukaemia-lymphoma

Ofatumumab is an anti-CD20 human monoclonal antibody that binds unique epitopes on CD20 with high specificity. CD20 antigen is expressed only on B-cell lymphocytes. CD20 antigen is expressed only on B-cell lymphocytes. Compared to rituximab, ofatumumab binds more tightly to CD20 and has a lower shut-down rate. It causes cytotoxicity in cells expressing CD20 through complement-dependent cytotoxicity (CDC) and antibody-dependent cytotoxicity (ADCC).
Blood cancers
Chronic Lymphocytic Leukaemia (CLL)
Chronic Lymphocytic Leukemia (CLL) - Refractory
Autoimmune diseases
Rheumatoid Arthritis
