What's a GeneRIF?

Mutations in TM1 and TM2 impaired the interaction of Tim17 with Tim23, component of the translocation channel, whereas mutations in TM3 compromised binding of the import motor. The authors identified residues in the matrix-facing region of Tim17 involved in binding of the import motor.

Overexpression of TIM17 prevents the complete loss of mtDNA in cells lacking Abf2.
Title: The conserved translocase Tim17 prevents mitochondrial DNA loss.
charged residues in Tim17 are critical for the preprotein-induced gating of the TIM23 translocase
Title: Conserved N-terminal negative charges in the Tim17 subunit of the TIM23 translocase play a critical role in the import of preproteins into mitochondria.
Tim17p is required for twin pore structure and provides the voltage gate for the TIM23 channel complex.
Title: Tim17p regulates the twin pore structure and voltage gating of the mitochondrial protein import complex TIM23.

Preferred Names: protein transporter TIM17

NP_012392.1

Essential core component of the TIM23 protein translocase complex; forms the protein translocation path with Mgr2p, while Tim23p contributes to the architecture of the import channel; may link the import motor to the core translocase of the inner mitochondrial membrane (TIM23 complex)
