PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	several phosphorylation sites in the N terminal region, and a unique serine-rich N-terminus
	C-terminal half contains two Ig-like domains homologous to titin
	shares the C-terminal motif E[ST][DE][D/E]L, which has the characteristics of a class III type PDZ domain binding sequence
	first Ig-domain of myotilin (MyoIg1), exhibits I-type Ig-fold , and Ig domains flanked with N- and C-terminal regions were needed for actin-bundling

HOMOLOGY

interspecies	ortholog to Myot, Mus musculus
	ortholog to MYOT, Pan roglodytes
	ortholog to Myot, Rattus norvegicus

Homologene

FAMILY

myotilin/palladin family

CATEGORY

motor/contractile , structural protein

SUBCELLULAR LOCALIZATION	plasma membrane
	intracellular
	intracellular,cytoplasm,cytoskeleton
text	sarcomeric protein
	localizes in sarcomeric Z-discs, where it interacts with several sarcomeric proteins

basic FUNCTION	myotilin plays a role in muscle contraction
	myotilin plays a role, in stabilization and anchorage of thin filaments, which may be a prerequisite for correct Z-disc organization
	core structural molecule in nemaline rods and central core lesions may be having a key role in the dynamic molecular events mediating myofibril assembly in normal and pathologic muscle
	has an important function in the assembly and maintenance of Z-discs

CELLULAR PROCESS	cell life, proliferation/growth

PHYSIOLOGICAL PROCESS

text	cell shape and cell size control

PATHWAY
