Mitochondrial transport is critical for maintenance of normal neuronal function. Here, we identify a novel mitochondria protein, hypoxia up-regulated mitochondrial movement regulator (HUMMR), which is expressed in neurons and is markedly induced by hypoxia-inducible factor 1 alpha (HIF-1alpha).

Mitochondrial distribution is integrally related to cellular function. Highly polarized cells, such as neurons, likely depend on mitochondrial transport to maintain proper synaptic function and neurite plasticity. In some cases, mitochondrial transport is also required for cellular migration and

Mitochondrial dysfunction is involved in aging and multiple degenerative diseases, including intervertebral disc degeneration (IVDD) and osteoarthritis (OA). Thus, the maintenance of mitochondria homeostasis and function is important. Mitophagy, a process that selectively clears damaged or
