Name :
Human ACVR1C/ALK7 Protein, ECD (Extracellular Domain), Fc-fusion, Biotinylated, 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 death. 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 two type-I and two type-II transmembrane receptors containing cytoplasmic serine/threonine kinase domains. These receptors are distinguished by the presence of a glycine/serine-rich juxta-membrane domain found only in the type I receptors. Either type receptor may initially bind ligand, followed by the recruitment of an alternate-type receptor counterpart to form a signal-activating complex. The type I receptors are also referred to as ALKs (Activin receptor-like kinases). ACVR1C (Activin receptor type-1C), also known as ALK7, ActR-IC, and ACVRLK7, is a type I receptor in the TGFβ receptor (TGFBR) family. ACVR1C acts as a type-I receptor to transduce signals of activin and Nodal. ACVR1C is expressed in pancreas, heart, colon, small intestine, ovary and brain. Upon ligand binding, ACVR1C associates with the type II receptor ACVR2A to form a signaling complex that activates AVCR1C through phosphorylation. The activated ACVR1C in turn initiates downstream events by phosphorylation of its effectors to regulate gene expression and affect cellular phenotype. ACVR1C may play an important role in cell differentiation, growth arrest and apoptosis.
