	a central alpha helical coiled coil (rod) domain
	a C-terminal tail consisiting of characteristic repeat sequences
	eleven plectin repeats
	a SH3 domain
	four spectrin repeats
	binding sites for both F-actin via its calponin homology (CH) domains and MTs via its GAS2-related (GAR) domain and/or GSR repeats

mono polymer

homomer , dimer

HOMOLOGY

interspecies	ortholog to murine dystonia musculorum gene (Dst)
	ortholog to murine cytoskeletal linker Bpag1
	homolog to C.elegans C50C3.2

Homologene

text	hemidesmosomes
	in sensory neurons localized in association with the ER and nuclear envelope (NE)

basic FUNCTION	acting as a cytoskeletal linker protein
	cytoskeletal interacting proteins play important roles in maintaining cytoarchitecture integrity in skin and in the neuromuscular system
	is a necessary endoplasmic reticulum/nuclear envelope protein in sensory neurons
	large multidomain cytoskeletal-associated protein that plays an essential role in the nervous system

CELLULAR PROCESS	cell cycle
	cell organization/biogenesis

PHYSIOLOGICAL PROCESS

text	cytoskeleton organization and biogenesis, cell cycle arrest

PATHWAY

metabolism

signaling

a component	constituent of cutaneous basement membrane zone
	component of hemidesmosome plaque
	forming filaments or a two-dimensional meshwork by self-aggregation

INTERACTION

DNA

RNA

small molecule	metal binding,
	calcium Ca2+

protein	binding to keratin intermediate filaments, actin
	interacting with COL17A1 (may help to anchor elements of the rod photoreceptor cytomatrix to the extracellular matrix)
	MAP1B, a microtubule stabilizing protein, and CLTC, the major component of the clathrin triskelion, are interaction partners for DST
