Genes affected

RPUSD3 (HGNC:28437): (RNA pseudouridine synthase D3) This gene encodes a protein that functions in the assembly of the mitochondrial ribosome by adding a pseudouridine group to 16S rRNA. Loss of this gene results in causes defects in mitochondrial protein production. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2017]

RPUSD3 links:

TTLL3 (HGNC:24483): (tubulin tyrosine ligase like 3) Enables protein-glycine ligase activity. Predicted to be involved in axoneme assembly and flagellated sperm motility. Predicted to be located in axoneme; microtubule cytoskeleton; and sperm flagellum. [provided by Alliance of Genome Resources, Apr 2022]
