重组Anti-Alpha Dystroglycan抗体[45-3] - BSA and Azide free

靶点信息

The dystroglycan complex is involved in a number of signaling events and processes including laminin deposition and extracellular matrix assembly, acetylcholine receptor (AChR) clustering, sarcolemmal stability, cell survival, peripheral nerve myelination, nodal structure, cell migration, epithelial polarization, and epithelium branching morphogenesis. Required for the formation of photoreceptor ribbon synapses, and long-term maintenance of inhibitory synapses in cerebellar Purkinje cells (PubMed : 18641643, PubMed : 40473926). Also involved in the positive regulation of cartilage formation through agrin (AGRN) binding and up-regulation of SOX9, a transcription factor that plays a key role in chondrocytes differentiation (By similarity).. Alpha-dystroglycan. Extracellular peripheral glycoprotein that acts as a receptor for extracellular matrix proteins containing laminin-G domains, and for certain adenoviruses. As a receptor for laminin is involved in extracellular matrix assembly, and activation of the PI3K/AKT pathway regulating cell apoptotic signals in muscle (PubMed : 10366602, PubMed : 12402286). Binding of laminin LAMA1 to alpha-dystroglycan also activates RAC1 signaling (PubMed : 16475793). This process involves a signaling cascade in which Src kinases, c-Src or c-Fyn, phosphorylate syntrophin modifying its interaction with the adapter protein GRB2; this triggers recruitment of guanyl-nucleotide exchange factor SOS1 and activation of RAC1, finally resulting in c-Jun phosphorylation by MAPK8/JNK1 (By similarity). As a receptor for laminin LAMA1 is also involved in epithelium branching morphogenesis in salivary glang and lung (PubMed : 11798066). Receptor for laminin-2 (LAMA2) and agrin in peripheral nerve Schwann cells (By similarity). Also acts as a receptor for laminin LAMA5 (By similarity) (PubMed : 10366602, PubMed : 11798066, PubMed : 12402286). In muscle cells, it is a receptor for laminin-1 (also known as laminin-111 or EHS laminin) and is involved in the stimulation of agrin-induced acetylcholine receptor (AChR) clustering, and formation of the synaptic basement membrane (PubMed : 16531403, PubMed : 9454835, PubMed : 11157973). It is required for acetylcholinesterase (AChE) localization at the neuromuscular junctions (NMJ) through its binding with perlecan (HSPG2) and is, therefore, involved in the down-regulation of colinergic synaptic transmission (PubMed : 11157973). In the retina, it is required for the formation of photoreceptor ribbon synapses through its interaction with pikachurin (EGFLAM) (PubMed : 18641643). Also involved in the positive regulation of cartilage formation through agrin (AGRN) binding and up-regulation of SOX9, a transcription factor that plays a key role in chondrocytes differentiation (By similarity).. Beta-dystroglycan. Transmembrane protein that plays important roles in connecting the extracellular matrix to the cytoskeleton. Acts as a cell adhesion receptor in both muscle and non-muscle tissues. Receptor for both DMD and UTRN and, through these interactions, scaffolds axin to the cytoskeleton. Also functions in cell adhesion-mediated signaling and implicated in cell polarity (By similarity).
