Membrane-embedded beta-barrel proteins span the membrane via multiple amphipathic beta-strands arranged in a cylindrical shape. These proteins are found in the outer membranes of Gram-negative bacteria, mitochondria and chloroplasts. This situation is thought to reflect the evolutionary origin of mitochondria and chloroplasts from Gram-negative bacterial(More)
Dopamine transporter mRNA expression in individual neurons from the substantia nigra pars compacta. 'All' area, arcuate nucleus of the hypothalamus, retina, and olfactory bulb was assessed by in situ hybridization. High levels of expression were noted over individual neurons in midbrain nuclei; much lower expression was found in cells of the inner nuclear(More)
The biological process of aging is believed to be the result of an accumulation of cellular damage to biomolecules. Although there are numerous studies addressing mutation frequencies, morphological or transcriptional changes in aging mammalian tissues, few have measured global changes at the protein level. Here, we present an in depth proteomic analysis of(More)
Structure and function of mitochondria are intimately linked. In a search for components that participate in building the elaborate architecture of this complex organelle we have identified Aim24, an inner membrane protein. Aim24 interacts with the MICOS complex that is required for the formation of crista junctions and contact sites between inner and outer(More)
The present study was performed to investigate the influence of intrastriatal fetal mesencephalic grafts on dopaminergic mRNA expression in the non-lesioned substantia nigra pars compacta of unilaterally 6-hydroxydopamine-lesioned rats. The expression of dopamine transporter mRNA, synaptic vesicular monoamine transporter mRNA and tyrosine hydroxylase mRNA(More)
