Subcellular Localization Mitochondrion outer membrane. Note=Its hydrophobic N-terminal sequence may be involved in membrane binding.
Disease Associations Hexokinase deficiency (HK deficiency) [MIM:235700]: Rare autosomal recessive disease with nonspherocytic hemolytic anemia as the predominant clinical feature. {ECO:0000269PubMed:12393545, ECO:0000269PubMed:7655856}. Note=The disease is caused by mutations affecting the gene represented in this entry.Hereditary motor and sensory neuropathy, Russe type (HMSNR) [MIM:605285]: An autosomal recessive progressive complex peripheral neuropathy characterized by onset in the first decade of distal lower limb weakness and muscle atrophy resulting in walking difficulties. Distal impairment of the upper limbs usually occurs later, as does proximal lower limb weakness. There is distal sensory impairment, with pes cavus and areflexia. Laboratory studies suggest that it is a myelinopathy resulting in reduced nerve conduction velocities in the demyelinating range as well as a length-dependent axonopathy. {ECO:0000269PubMed:19536174}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Isoform 2 is erythrocyte specific. Isoform 3 and isoform 4 are testis-specific.
