Genes affected

FASTKD5 (HGNC:25790): (FAST kinase domains 5) Enables rRNA binding activity. Involved in mitochondrial RNA processing. Located in mitochondrial nucleoid and ribonucleoprotein granule. [provided by Alliance of Genome Resources, Apr 2022]

FASTKD5 links:

UBOX5 (HGNC:17777): (U-box domain containing 5) This gene encodes a U-box domain containing protein. The encoded protein interacts with E2 enzymes and may play a role in the ubiquitination pathway. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jun 2012]
