Species Reactivity
> 90% by SDS-PAGE & silver stain
The lyophilized sBMPR-1A is soluble in water and most aqueous buffers and should be reconstituted in PBS or medium to a concentration not lower than 50ug/ml.
Biological Activity
Measured by its ability to inhibit recombinant human BMP-2 induced alkaline phosphatase production by C2C12 myogenic cells. The ED50 for this effect is typically 1-4 ug/ml in the presence of 500ng/ml of recombinant human BMP-2.
Preparation and Storage
Lyophilized samples are stable for greater than six months at -20 degree C to -70 degree C. Reconstituted sBMPR-1A should be stored in working aliquots at -20 degree C.
ISO Certification
Manufactured in an ISO 9001:2015 Certified Laboratory.
Other Notes
Small volumes of BMP receptor-1A recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

BMP receptor-1A recombinant protein
The extracellular domain of human BMPR-IA was fused with a carboxy-terminal 6X histidine-tag. The monomeric glycoprotein was expressed in baculovirus infected insect cells. Cellular responses to bone morphogenetic proteins (BMPs) have been shown to be mediated by the formation of hetero-oligomeric complexes of the type I and type II serine/threonine kinase receptors. BMP receptor 1A (BMPR-1A), also known as activin receptor-like kinase (ALK)-3, is a one of seven known type I serine/threonine kinases that are required for the signal transduction of TGF-b family cytokines. In contrast to the TGF-b receptor system in which the type I receptor does not bind TGF-b in the absence of the type II receptor, type I receptors involved in BMP signaling (including BMPR-IA, BMPR-IB/ALK-6, and ActR-I/ALK-2) can independently bind the various BMP family proteins in the absence of type II receptors. Recombinant soluble BMPR-IA binds BMP-2 and -4 with high-affinity in solution and is a potent BMP-2/4 antagonist in vitro. BMPR-IA is ubiquitously expressed during embryogenesis. In adult tissues, BMPR-IA mRNA is also widely distributed; with the highest expression levels found in skeletal muscle. The extracellular domain of BMPR-IA shares little amino acid sequence identity with the other mammalian ALK type I receptor kinases, but the cysteine residues are conserved. Human and mouse BMPR-IA are highly conserved and share 98% sequence identity.

BMP-2 BioLISA using recombinant human soluble BMPR-IA for capturing and recombinant human BMP-2 as standard. A rabbit anti-human BMP-2 antibody in combination with an goat anti-rabbit Biotin antibody was used for detection.

NCBI Summary for BMP receptor-1A
The bone morphogenetic protein (BMP) receptors are a family of transmembrane serine/threonine kinases that include the type I receptors BMPR1A and BMPR1B and the type II receptor BMPR2. These receptors are also closely related to the activin receptors, ACVR1 and ACVR2. The ligands of these receptors are members of the TGF-beta superfamily. TGF-betas and activins transduce their signals through the formation of heteromeric complexes with 2 different types of serine (threonine) kinase receptors: type I receptors of about 50-55 kD and type II receptors of about 70-80 kD. Type II receptors bind ligands in the absence of type I receptors, but they require their respective type I receptors for signaling, whereas type I receptors require their respective type II receptors for ligand binding.

UniProt Comments for BMP receptor-1A
Function: On ligand binding, forms a receptor complex consisting of two type II and two type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors which autophosphorylate, then bind and activate SMAD transcriptional regulators. Receptor for BMP-2 and BMP-4.

Catalytic activity: ATP + [receptor-protein] = ADP + [receptor-protein] phosphate.

Cofactor: Magnesium or manganese

By similarity.

Subcellular location: Membrane; Single-pass type I membrane protein.

Tissue specificity: Highly expressed in skeletal muscle.

Involvement in disease: Juvenile polyposis syndrome (JPS) [MIM:174900]: Autosomal dominant gastrointestinal hamartomatous polyposis syndrome in which patients are at risk for developing gastrointestinal cancers. The lesions are typified by a smooth histological appearance, predominant stroma, cystic spaces and lack of a smooth muscle core. Multiple juvenile polyps usually occur in a number of Mendelian disorders. Sometimes, these polyps occur without associated features as in JPS; here, polyps tend to occur in the large bowel and are associated with an increased risk of colon and other gastrointestinal cancers.Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.6 Ref.7 Ref.8 Ref.9 Ref.10Polyposis syndrome, mixed hereditary 2 (HMPS2) [MIM:610069]: A disease is characterized by atypical juvenile polyps, colonic adenomas, and colorectal carcinomas.Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.6A microdeletion of chromosome 10q23 involving BMPR1A and PTEN is a cause of chromosome 10q23 deletion syndrome, which shows overlapping features of the following three disorders: Bannayan-Zonana syndrome, Cowden disease and juvenile polyposis syndrome.

Sequence similarities: Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. TGFB receptor subfamily.Contains 1 GS domain.Contains 1 protein kinase domain.
