MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the globin superfamily and is expressed in skeletal and cardiac muscles. The encoded protein is a haemoprotein contributing to intracellular oxygen storage and transcellular facilitated diffusion of oxygen. At least three alternatively spliced transcript variants encoding the same protein have been reported. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes for a null allele show increased cardiac capillary density, coronary flow, hemoglobin and hematocrit levels. Many mice homozygous for another null allele die of heart failure at midgestation; survivors show hypervascularity, altered NO metabolism, and hypoxia-induced cardiac dysfunction.
