    Activin, a disulfide-linked homodimeric protein is secreted by Sertoli cells in the testis and granulosa cells in the ovary. In early studies, this peptide was thought to be an inhibin and not recognized as a unique compound. Activins and inhibins are members of the TGF-beta superfamily due to amino acid homology with respect to the conservation of 7 of the 9 cysteine residues common to all TGF-beta forms. Activins are homodimers or heterodimers of the various beta subunit isoforms, while inhibins are heterodimers of a unique alpha subunit and one of the various beta subunits. Five beta subunits have been cloned (mammalian beta A, beta B, beta C, beta E, and Xenopus beta D). The activin/inhibin nomenclature reflects the subunit composition of the proteins: activin A (beta A-beta A), activin B (beta B-beta B), activin AB (beta B-beta A), inhibin A (alpha-beta A) abd inhibin B (alpha-beta B). Activins have a wide range of biological activities including mesoderm induction neural cell differentiation, bone remodeling, hematopoiesis, and reproductive physiology. Activins are also involved in growth and differentiation of several tissues from different species. This protein also plays a key role in the production and regulation of hormones such as FSH, LH, GnRH, and ACTH. Activin influences erythropoiesis and the potentiation of erythroid colony formation, oxytocin secretion, paracrine, and autocrine regulation. Similar to other TGF-beta family members, activins exert their biological activities through the effects of the heterodimeric complex composed of two membrane spanning serine-threonine kinases designated type I and type II receptors. Activin type I and type II receptors are distinguished by the level of sequence homology of their kinase domains and other structural and functional features. To date, seven type I and five type II activin receptors have been cloned from mammals, including activin receptor IA, activin receptor IIA, activin receptor IB, and activin receptor IIB. In addition, two splice variants of activin receptor IIA and five splice variants of activin receptor IIB have been reported. Type I activin receptors do not bind directly to activin but will associate with the type II receptor-activin complex and initiate signal transduction. Recombinant soluble activin type II receptors bind activin with high affinity and are potent activin antagonists. Activin type II receptors are highly conserved and will also bind inhibin, BMP2, and BMP7 with lower affinities. Human, mouse, and rat type II activin receptors share 98 % homology.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

アプリケーション Abreviews 特記事項
IHC-P Use at an assay dependent dilution. PubMed: 19638618
Indirect ELISA Use a concentration of 0.5 - 1 µg/ml.
WB Use a concentration of 0.1 - 0.2 µg/ml. Predicted molecular weight: 58 kDa. ~1 ng/lane under non-reducing and reducing conditions.
Neutralising Use a concentration of 1 - 3 µg/ml. The antibody will block 50% of the binding of 30 ng/ml recombinant human activin A to immobilized recombinant human activin receptor IIB/Fc chimera (100 µL of 50 µg/ml solution coating each well) in a functional ELISA assay. ab10596 has not been optimized for cell/tissue culture conditions.

ターゲット情報

  • 機能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 activin A, activin B and inhibin A.
  • 関連疾患Defects in ACVR2B are the cause of visceral heterotaxy autosomal type 4 (HTX4) [MIM:613751]. A form of visceral heterotaxy, a complex disorder due to disruption of the normal left-right asymmetry of the thoracoabdominal organs. It results in an abnormal arrangement of visceral organs, and a wide variety of congenital defects. Clinical features of visceral heterotaxy type 4 include dextrocardia, right aortic arch and a right-sided spleen, anomalies of the inferior and the superior vena cava, atrial ventricular canal defect with dextro-transposed great arteries, pulmonary stenosis, polysplenia and midline liver.
