ALK-2/ACVR1 概述&蛋白信息

ALK-2/ACVR1 研究背景

基因概述: Activins 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. ACVR1 gene encodes activin A type I receptor which signals a particular transcriptional response in concert with activin type II receptors. Mutations in this gene are associated with fibrodysplasia ossificans progressive. [provided by RefSeq, Jul 2008]
General information above from NCBI
催化活性: ATP + [receptor-protein] = ADP + [receptor- protein] phosphate.
輔因數: Magnesium or manganese (By similarity).
亞單位結構: Interacts with FKBP1A. Interacts with FCHO1.
亞細胞定位: Membrane; Single-pass type I membrane protein.
組織特異性: Expressed in normal parenchymal cells, endothelial cells, fibroblasts and tumor-derived epithelial cells.
相關疾病 : Fibrodysplasia ossificans progressiva (FOP) [MIM:135100]: A rare autosomal dominant connective tissue disorder resulting in skeletal malformations and progressive extraskeletal ossification. Heterotopic ossification begins in childhood and can be induced by trauma or may occur without warning. Bone formation is episodic and progressive, leading to a debilitating ankylosis of all major joints of the axial and appendicular skeleton, rendering movement impossible. Note=The disease is caused by mutations affecting the gene represented in this entry.
相似的序列: Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. TGFB receptor subfamily.
Contains 1 GS domain.
Contains 1 protein kinase domain.

ALK-2, also termed as ACVR1, was initially identified as an activin type I receptor because of its ability to bind activin in concert with ActRII or ActRIIB. ALK-2 is also identified as a BMP type I receptor. It has been demonstrated that ALK-2 forms complex with either the BMP-2/7-bound BMPR-II or ACVR2A /ACVR2B. ALK-1 and ALK-2 presenting in the yeast Saccharomyces cerevisiae are two haspin homologues. Both ALK-1 and ALK-2 exhibit a weak auto-kinase activity in vitro, and are phosphoproteins in vivo. ALK-1 and ALK-2 levels peak in mitosis and late-S/G2. Control of protein stability plays a major role in ALK-2 regulation. The half-life of ALK-2 is particularly short in G1. Overexpression of ALK-2, but not of ALK-1, causes a mitotic arrest, which is correlated to the kinase activity of the protein. This suggests a role for ALK-2 in the control of mitosis. Endoglin is phosphorylated on cytosolic domain threonine residues by the TGF-beta type I receptors ALK-2 and ALK-5 in prostate cancer cells. Endoglin did not inhibit cell migration in the presence of constitutively active ALK-2. Defects in ALK-2 are a cause of fibrodysplasia ossificans progressiva (FOP).
