Cooperation Seeking

Creative Biolabs is interested in collaborating with potential partners (include but not limit to major pharma or biotech firms) to further co-develop ADCC-enhanced rituximab. For commercial partners interested in our ADCC-enhanced therapeutic antibodies, Creative Biolabs welcomes collaboration. Here are two ways for your choice, and please contact us for more details.
1) Collaborate with us and co-develop the programs from discovery phase to IND enabling. Costs will be shared.
2) Become a licensed candidate of our programs.
Looking forward to cooperating with you in the near future.
Official Name
Full Name
membrane spanning 4-domains A1
This gene encodes a member of the membranespanning 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 Blymphocyte surface molecule which plays a role in the development and differentiation of Bcells 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).

Species Reactivity
Ocrelizumab, trade name Ocrvus, is a humanized anti-CD20 monoclonal antibody. It targets the CD20 marker on B lymphocytes and is therefore an immunosuppressive drug. It was developed by Genentech / Roche and was approved by the FDA in March 2017 for the treatment of multiple sclerosis.
Multiple Sclerosis, Primary Progressive
Relapsing Multiple Sclerosis (RMS)

Ocrelizumab is a second-generation recombinant humanized monoclonal IgG1 antibody that selectively targets B lymphocytes that express the CD20 antigen. B lymphocytes are known to promote the pathogenesis of MS by activating pro-inflammatory T cells and secreting pro-inflammatory cytokines. Ocrelizumab promotes cytotoxicity of antibody-dependent cells and complement-mediated cell lysis by binding to CD20-expressing B lymphocytes. Ocrelizumab may induce antibody-dependent cytotoxicity, involving macrophages, natural killer cells, and cytotoxic T cells that work together to cause cell death.
