This document summarizes a study on the localization and potential functions of two proteins, VDAC4 and TGrPE1, in the ciliated protozoan Tetrahymena thermophilia. VDAC4 encodes a porin protein that localizes to mitochondria and basal bodies, suggesting a role in mitochondrial-ciliary transport. TGrPE1 encodes a protein containing a GrPE1 domain that may regulate chaperone proteins through ATP/ADP exchange, and it localizes near mitochondria. The goal is to better understand the roles of these proteins in mitochondrial processes and protein folding in Tetrahymena.
