Summary: Predicted to enable alpha-actinin binding activity and cell-cell adhesion mediator activity. Predicted to be involved in axon guidance; dendrite self-avoidance; and homophilic cell adhesion via plasma membrane adhesion molecules. Located in Z disc. Is expressed in several structures, including embryo mesenchyme; gut; lung; mesonephros; and nervous system. Human ortholog(s) of this gene implicated in muscular dystrophy; myofibrillar myopathy 3; and spheroid body myopathy. Orthologous to human MYOT (myotilin).

GeneRIFs: Gene References Into Functions

What's a GeneRIF?

Myotilin does not have a significant influence on muscle mass, muscle fiber size, or regulation of muscle contraction. Alternatively, compensatory over-expressions of other elements may compensate for the lack of myotilin.
Title: Maintenance of muscle mass, fiber size, and contractile function in mice lacking the Z-disc protein myotilin.
In single-transgenic mutant mice, double-transgenic mice overexpressing myotilin showed more severe muscle degeneration, enhanced myofibrillar aggregation, and earlier onset of aggregation.
Title: Myotilin overexpression enhances myopathology in the LGMD1A mouse model.
either myotilin does not participate in muscle development and basal function maintenance or other proteins serve as structural and functional compensatory molecules when myotilin is absent
Title: Targeted deletion of the muscular dystrophy gene myotilin does not perturb muscle structure or function in mice.
features suggest an important role for myotilin in sarcomere organization.
Title: Characterization of mouse myotilin and its promoter.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
