Dok-7 Rabbit Polyclonal Antibody

Docking protein 7 (DOK7) Homo sapiens The protein encoded by this gene is essential for neuromuscular synaptogenesis. The protein functions in aneural activation of muscle-specific receptor kinase, which is required for postsynaptic differentiation, and in the subsequent clustering of the acetylcholine receptor in myotubes. This protein can also induce autophosphorylation of muscle-specific receptor kinase. Mutations in this gene are a cause of familial limb-girdle myasthenia autosomal recessive, which is also known as congenital myasthenic syndrome type 1B. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2009], disease:Defects in DOK7 are the cause of familial limb-girdle myasthenia autosomal recessive (LGM) [MIM:254300]; also called congenital myasthenic syndrome type 1B or CMS1B. LGM is a congenital myasthenic syndrome characterized by a typical 'limb girdle' pattern of muscle weakness with small, simplified neuromuscular junctions but normal acetylcholine receptor and acetylcholinesterase function., function:Probable muscle-intrinsic activator of MUSK that plays an essential role in neuromuscular synaptogenesis. Acts in aneural activation of MUSK and subsequent acetylcholine receptor (AchR) clustering in myotubes. Induces autophosphorylation of MUSK., similarity:Contains 1 IRS-type PTB domain., similarity:Contains 1 PH domain., subcellular location:Accumulates at neuromuscular junctions., subunit:Interacts with the cytoplasmic part of MUSK., tissue specificity:Preferentiall eypressed in skeletal muscle and heart Present in thigh muscle, diaphragm and heart but not in the liver or spleen (at protein level) .
