{"product_id":"new-product-280491","title":"ACVR2B polyclonal antibody","description":"\u003cp\u003eActivins are dimeric growth and differentiation factors which belong to the transforming growth factor-beta (TGF-beta) superfamily of structurally related signaling proteins. Activins signal through a heteromeric complex of receptor serine kinases which include at least two type I (I and IB) and two type II (II and IIB) receptors. These receptors are all transmembrane proteins, composed of a ligand-binding extracellular domain with cysteine-rich region, a transmembrane domain, and a cytoplasmic domain with predicted serine\/threonine specificity. Type I receptors are essential for signaling; and type II receptors are required for binding ligands and for expression of type I receptors. Type I and II receptors form a stable complex after ligand binding, resulting in phosphorylation of type I receptors by type II receptors. Type II receptors are considered to be constitutively active kinases. This gene encodes activin A type IIB receptor, which displays a 3- to 4-fold higher affinity for the ligand than activin A type II receptor.\u003c\/p\u003e","brand":"ABCbiolab","offers":[{"title":"100ul \/ Rabbit \/ Human","offer_id":45808679289112,"sku":"ABCBW08581","price":408.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/758-7580448_monoclonal-antibody-png-transparent-png_7db743b3-036c-432b-9066-f25c901421c2.png?v=1689752204","url":"https:\/\/danabiosci.com\/products\/new-product-280491","provider":"Dana Bioscience","version":"1.0","type":"link"}
