A later study indicated that in lung cancer, Tid-1-S, a short form of Tid1 also known as mitochondrial heat shock protein 40 (mtHSP40), interacts with EGFR in the cytosol and governs EGFR translocation into the mitochondria, where an EGFR/Tid1-S/mtHSP70 complex enhances cell metastasis and tumor progression [123]. Here, DNAJA3 is linked to lung cancer.
