Description
Promotes mitochondrial protein synthesis. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Binds to mitochondrial ribosomes in a GTP-dependent manner.
Plays a role in promoting axonal degeneration following neuronal injury by toxic insult or trauma (PubMed:22496551). Organizes rhabdomeric components to suppress random activation of the phototransduction cascade and thus increases the signaling fidelity of dark-adapted photoreceptors (PubMed:20107052). The rtp/ninaC complex is required for stability of inad and inac and the normal termination of phototransduction in the retina (PubMed:20739554).
