ACVR1



Activin receptor type-1
Other names:Activin receptor type I, ACTR-I, Serine/threonine-protein kinase, receptor R1, SKR1, Activin receptor-like kinase 2, ALK-2, TGF-B superfamily receptor type I, TSR-I
Genetic data
Gene code: HUGO code:ACVR1
Protein Structure/Function
Protein type: Serine/Threonine receptor kinase
Domains: GS domain, TS domain, S/T domain
Other
Taxa expressing:Homo sapiens; homologs: many metazoan phyla
Cell types:ubiquitous
Subcellular localization:Plasma membrane
Enzymatic Data
Catalytic activity:ATP + (receptor-protein) = ADP + (receptor-protein) phosphate
Cofactor(s):Magnesium or manganese
Medical/Biotechnological data
Diseases:Fibrodysplasia ossificans progressiva (FOP) Online 'Mendelian Inheritance in Man' (OMIM) 135100

ACVR1 or ALK-2 transduces signals of BMPs. BMPs bind either ACVR2A/ACVR2B or a BMPR2 and then form a complex with ACVR1. These go on to recruit the R-SMADs SMAD1, SMAD2, SMAD3 or SMAD6[1]
