Recombinant Human Dystonin (DST), partial

Function

Regulates the organization and stability of the microtubule network of sensory neurons to allow axonal transport

Subcellular Location

Cytoplasm, cytoskeleton; Cytoplasm, cell cortex; Cell membrane (Lipid-anchor)

Disease Association

Neuropathy, hereditary sensory and autonomic, 6 (HSAN6) : A form of hereditary sensory and autonomic neuropathy, a genetically and clinically heterogeneous group of disorders characterized by degeneration of dorsal root and autonomic ganglion cells, and by sensory and/or autonomic abnormalities. HSAN6 is a severe autosomal recessive disorder characterized by neonatal hypotonia, respiratory and feeding difficulties, lack of psychomotor development, and autonomic abnormalities including labile cardiovascular function, lack of corneal reflexes leading to corneal scarring, areflexia, and absent axonal flare response after intradermal histamine injection. [The disease is caused by variants affecting the gene represented in this entry] | Epidermolysis bullosa simplex 3, localized or generalized intermediate, with BP230 deficiency (EBS3) : A form of epidermolysis bullosa, a genodermatosis characterized by recurrent blistering, fragility of the skin and mucosal epithelia, and erosions caused by minor mechanical trauma. EBS3 is an autosomal recessive disorder characterized by skin blistering mainly occurring on the feet and ankles. Ultrastructural analysis of skin biopsy shows abnormal hemidesmosomes with poorly formed inner plaques. [The disease is caused by variants affecting the gene represented in this entry]

Tissue Specificity

Isoform 1 is expressed in myoblasts (at protein level). Isoform 3 is expressed in the skin. Isoform 6 is expressed in the brain. Highly expressed in skeletal muscle and cultured keratinocytes

Subunit

Homodimer. Isoform 1 interacts (via N-terminus) with PLEC (via N-terminus). Interacts with the neuronal intermediate filament protein, PRPH. Interacts with DES. Interacts with SYNE3 (By similarity). Isoform 1 and isoform 6 can homodimerize (via N-terminus). Isoform 1 interacts (via N-terminus) with ACTN2. Isoform 1 interacts (via N-terminus) with PLEC (via N-terminus). Isoform 3 interacts (via N-terminus) with COL17A1 (via cytoplasmic region). Isoform 3 interacts (via N-terminus) with ITGB4 isoform beta-4a (via cytoplasmic region). Isoform 3 interacts (via N-terminus) with ERBIN (via C-terminus). Isoform 3 associates (via C-terminal) with KRT5-KRT14 (via rod region) intermediate filaments of keratins. Interacts with MAPRE1; probably required for targeting to the growing microtubule plus ends. Interacts with TMIGD2. Isoform 9 interacts with TMEM108 (By similarity)
