Name :
Human TGFB1/TGFβ1-LAP Protein Complex, Biotinylated, Fc-fusion, Recombinant
Description :
The TGFβ (transforming growth factor β) superfamily proteins are pleiotropic cytokines that regulate a diverse range of cellular processes, including proliferation, differentiation, migration, adhesion and apoptosis. The TGFβ superfamily elicits 4 signaling pathways: TGFβ, Bone Morphogenic Protein (BMP), Activin, and Nodal. Each pathway signals through a heteromeric receptor complex composed of at least 2 type-I and 2 type-II receptors with cytoplasmic serine/threonine kinase domains. The receptor complex phosphorylates and activates Smad proteins to regulate downstream gene transcription. There are 3 closely related mammalian members (TGFβ1-3) of the TGFβ family that share a characteristic cystine knot structure. They are known to function as cellular switches that regulate immune function, proliferation and epithelialmesenchymal transition (EMT). Each TGFβ isoform has non-redundant functions. For instance, TGFβ1-deficient mice display defects in hematopoiesis and endothelial differentiation, and die of overwhelming inflammation. TGFβ1 is highly expressed in bone and acts as a stimulator of bone formation. A furinlike convertase processes it to generate an Nterminal 249 aa latencyassociated peptide (LAP) and a Cterminal 112 aa mature TGFβ1. Mature human TGFβ1 is 100% identical to pig, dog and cow TGFβ1, and 99% identical to mouse, rat and horse TGFβ1, therefore showing crossspecies activity. TGFβs are identified as potential therapeutic targets for cancer and cardiovascular diseases. This gene is frequently upregulated in tumor cells, and mutations in this gene result in Camurati-Engelmann disease.

Uniprot Entry :
P01137
Construct Details :
The recombinant human TGFB1-Fc fusion is expressed as a 600 amino acid protein consisting of Leu30 – Ser390 region of TGFB1 (Uniprot Accession #P01137) and a C-terminal Fc from human IgG1, which exists as a disulfide-linked dimeric LAP-TGFβ1-Fc complex under non-reducing conditions.
