Is predicted to encode a protein with the following domains: Mediator of RNA polymerase II transcription subunit 15 and ARC105 or Med15 subunit of Mediator complex non-fungal. Is an ortholog of C. elegans mdt-15. In C. elegans, mdt-15 is involved in several processes, including determination of adult lifespan; regulation of primary metabolic process; and sequestering of triglyceride.
