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