Protein Coding Gene : Myh7b myosin, heavy chain 7B, cardiac muscle, beta

Primary Identifier  MGI:3710243 Organism  mouse, laboratory
Chromosome  2 NCBI Gene Number  668940
Mgi Type  protein coding gene
description  FUNCTION: Automated description from the Alliance of Genome Resources (Release 7.0.0)

Predicted to enable actin filament binding activity and microfilament motor activity. Predicted to be involved in regulation of CAMKK-AMPK signaling cascade; regulation of cardiac muscle cell contraction; and regulation of cytosolic calcium ion concentration. Located in cardiac myofibril. Is expressed in several structures, including autopod; embryo mesenchyme; heart; lens; and musculature. Human ortholog(s) of this gene implicated in hypertrophic cardiomyopathy. Orthologous to human MYH7B (myosin heavy chain 7B).
PHENOTYPE: Homozygous knockout does not affect heart development, but exogenous expression in cardiomyocytes leads to increased atrial and ventricular weights, left ventricular dilation and decreased fractional shortening. [provided by MGI curators]
