About our lab

Loyola Marymount University

Mitochondria produce most of the energy a cell runs on, but they cannot build most of their own machinery. Around a thousand of their proteins are assembled elsewhere in the cell and imported. We work on that import machinery in budding yeast: how it recognizes its cargo, how it uses chemistry to pull a protein across a membrane, and what fails when it breaks. Import failures are implicated in human disease, so mapping the healthy process is the prerequisite for understanding the broken one.

Research

All research

01

Protein import

How the machinery of the mitochondrial intermembrane space recognizes the proteins it is meant to take in, and how it holds onto them once they are across.

02

Redox-regulated translocation

The Mia40-Erv1 disulfide relay and the electron acceptors that keep it turning over, among them cytochrome c, cytochrome c peroxidase, and Osm1.

03

Aim32

A dual-localized 2Fe-2S thioredoxin-like ferredoxin. We are working out what it does in mitochondrial biogenesis, in respiration, and in the assembly of the mitoribosome.

The lab

The lab is run by undergraduates. About six student researchers work here at a time, on budding yeast in part because it is a system an undergraduate can actually run. They present their own findings at conferences, and several have become authors on their own papers.

An accomplished teacher-scholar, Dabir has mentored numerous undergraduate researchers, many of whom have become co-authors on peer-reviewed publications.
