DAG1 rabbit pAb

This gene encodes dystroglycan, a central component of dystrophin-glycoprotein complex that links the extracellular matrix and the cytoskeleton in the skeletal muscle. The encoded preproprotein undergoes O- and N-glycosylation, and proteolytic processing to generate alpha and beta subunits. Certain mutations in this gene are known to cause distinct forms of muscular dystrophy. Alternative splicing results in multiple transcript variants, all encoding the same protein.

[Alpha-dystroglycan]: Secreted, extracellular space.; [Beta-dystroglycan]: Cell membrane ; Single-pass type I membrane protein. Cytoplasm, cytoskeleton. Nucleus, nucleoplasm . Cell membrane, sarcolemma . Cell junction, synapse, postsynaptic cell membrane . The monomeric form translocates to the nucleus via the action of importins and depends on RAN. Nuclear transport is inhibited by Tyr-892 phosphorylation. In skeletal muscle, this phosphorylated form locates to a vesicular internal membrane compartment. In muscle cells, sarcolemma localization requires the presence of ANK2, while localization to costameres requires the presence of ANK3. Localizes to neuromuscular junctions (NMJs) in the presence of ANK2 (By similarity) . In peripheral nerves, localizes to the Schwann cell membrane. Colocal
