Summaries for RIOK3 Gene

Entrez Gene Summary for RIOK3 Gene

  • This gene was identified by the similarity of its product to the Aspergillus nidulans SUDD protein, an extragenic suppressor of the heat-sensitive bimD6 mutation that fails to attach properly to the spindle microtubules at a restrictive temperature. The specific function of this gene has not yet been determined. [provided by RefSeq, Jul 2008]

GeneCards Summary for RIOK3 Gene
