Papers on Tom20
Bax assembles into large ring-like structures remodeling the mitochondrial outer membrane in apoptosis.

Norcantharidin Inhibits SK-N-SH Neuroblastoma Cell Growth by Induction of Autophagy and Apoptosis.
Jiang et al., Guangzhou, China. In Technol Cancer Res Treat, Feb 2016
In the present study, norcantharidin suppressed the proliferation and cloning ability of SK-N-SH cells in a dose-dependent manner, apparently by reducing the mitochondrial membrane potential and arresting SK-N-SH cells at the G2/M stage, accompanied by elevated expressions of p21 and decreased expressions of cyclin B1 and cell division control 2. Treatment by norcantharidin induced significant mitophagy and autophagy, as demonstrated by a decrease in Translocase Of Outer Mitochondrial Membrane 20 (TOM20), increased beclin1 and LC3-II protein expression, reduced protein SQSTM1/p62 expression, and accumulation of punctate LC3 in the cytoplasm of SK-N-SH cells.
Rational design of crystal contact-free space in protein crystals for analyzing spatial distribution of motions within protein molecules.
Kohda et al., Fukuoka, Japan. In Protein Sci, Jan 2016
We applied the CCFS method to a highly mobile presequence peptide bound to the mitochondrial import receptor, Tom20, and a catalytically relevant flexible segment in the oligosaccharyltransferase, AglB.
Counteracting PINK/Parkin deficiency in the activation of mitophagy: a potential therapeutic intervention for Parkinson's Disease.

Transgenic Zebrafish Expressing mCherry in the Mitochondria of Dopaminergic Neurons.
Ekker et al., Ottawa, Canada. In Zebrafish, Oct 2015
To visualize mitochondria in dopaminergic neurons of live zebrafish, we used the regulatory elements of the dopamine transporter (dat) gene to target a reporter, mCherry, after fusion with the mitochondrial localizing signal (MLS) of Tom20.
PINK1 and Parkin control localized translation of respiratory chain component mRNAs on mitochondria outer membrane.
Lu et al., Stanford, United States. In Cell Metab, Feb 2015
Translationally repressed nRCC mRNAs are localized in a PINK1/Tom20-dependent manner to mitochondrial outer membrane, where they are derepressed and activated by PINK1/Parkin through displacement of translation repressors, including Pumilio and Glorund/hnRNP-F, a Parkin substrate, and enhanced binding of activators such as eIF4G.
Glucose-induced regulation of protein import receptor Tom22 by cytosolic and mitochondria-bound kinases.
Meisinger et al., Freiburg, Germany. In Cell Metab, 2013
CK1 phosphorylates Tom22 at Thr57 and stimulates the assembly of Tom22 and Tom20.
Unique components of the plant mitochondrial protein import apparatus.
Whelan et al., Crawley, United Kingdom. In Biochim Biophys Acta, 2013
This includes the evolution of two unique outer membrane import receptors, plant Translocase of outer membrane 20 kDa subunit (TOM20) and Outer membrane protein of 64 kDa (OM64), the loss of a receptor domain from an ancestral import component, Translocase of outer membrane 22 kDa subunit (TOM22), evolution of unique features in the disulfide relay system of the inter membrane space, and the addition of an extra membrane spanning domain to another ancestral component of the inner membrane, Translocase of inner membrane 17 kDa subunit (TIM17).

Dual role of the receptor Tom20 in specificity and efficiency of protein import into mitochondria.
Endo et al., Nagoya, Japan. In Proc Natl Acad Sci U S A, 2011

Structure, topology and function of the translocase of the outer membrane of mitochondria.
Gooley et al., Melbourne, Australia. In Plant Physiol Biochem, 2008
Recently, bioinformatic and structural analysis of Tom20, an important receptor subunit of the TOM complex, suggests that this protein complex arose from different ancestors for plants compared to animals and fungi, but has subsequently converged to provide similar functions and analogous structures.

Lithgow et al., Melbourne, Australia. In J Mol Biol, 2008

Functions of outer membrane receptors in mitochondrial protein import.
Kohda et al., Nagoya, Japan. In Biochim Biophys Acta, 2002
The recently determined NMR structure of the general import receptor Tom20 in a complex with a presequence peptide reveals that, although the amphiphilicity and positive charges of the presequence is essential for the import ability of the presequence, Tom20 recognizes only the amphiphilicity, but not the positive charges.
