BAFF protein is expressed in B-cell lineage cells which functions as a cytokine and is also a member of the tumor necrosis factor (TNF) family of ligands. The BAFF cytokine acts as a potent B-cell activator promoting the proliferation and differentiation of B-cells. This protein is expressed as a membrane-bound type II transmembrane protein on various cell types including monocytes, dendritic cells and bone marrow stromal cells. The membrane bound form can be cleaved from the membrane, generating a soluble protein fragment. BAFF steady-state concentrations depend on B‑cells and also on the expression of BAFF-binding receptors.\u003cbr\u003e\nInadequate levels of BAFF will fail to activate B-cells to produce enough immunoglobulin and will lead to immunodeficiency. Excessive level of BAFF causes abnormally high antibody production, results in systemic lupus erythmatosis, rheumatoid arthritis, and many other autoimmune diseases.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions-+4°C, Appropriate long-term storage conditions-+4°C, Storage information-+4°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nBAFF also known as B-cell activating factor or TNFSF13B is a protein important for B-cell survival and maturation. It's a type II transmembrane protein expressed in cells like macrophages and dendritic cells and has a mass of approximately 31 kDa. The BAFF protein is also present on activated T-cells and in the serum as a soluble form. It functions as a cytokine and influences various stages of B-cell development.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nBAFF plays a significant role in the humoral immune response by enhancing B-cell proliferation and function. It belongs to the tumor necrosis factor (TNF) ligand family and interacts as a homotrimer. The BAFF cytokine can bind to receptors such as BAFF-R BCMA (B-cell maturation antigen) and TACI (transmembrane activator and CAML interactor). These interactions regulate B-cell homeostasis promoting development and differentiation processes important for normal immune responses.\u003cbr\u003e\nPathways\u003cbr\u003e\nBAFF is central to the regulation of immune system signaling particularly in B-cell receptor (BCR) signaling and NF-kB pathway activation. The BAFF-R mediates B-cell survival signals through the NF-kB pathway while TACI and BCMA associations convey additional immune responses regulation. These multiple pathways ensure the maintenance of B-cell populations and their ability to produce antibodies.\u003cbr\u003e\nBAFF has been linked to conditions such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Elevated levels of BAFF can exacerbate autoimmune responses due to increased B-cell survival. Connections with these disorders involve the BAFF-R and its influence on excessive B-cell proliferation contributing to disease pathology. Therapeutically anti-BAFF therapies target these interactions to modify disease progression and manage autoimmunity.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843646738601,"sku":"ab188391","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab188391","provider":"Iright","version":"1.0","type":"link"}
