ATP-dependent RNA helicase SUPV3L1, mitochondrial (SUPV3L1)

Major helicase player in mitochondrial RNA metabolism. Component of the mitochondrial degradosome (mtEXO) complex, that degrades 3' overhang double-stranded RNA using a 3'-to-5' directionality in an ATP-dependent method.

ATPase and ATP- dependent multisubstrate helicase, able to unwind double-stranded (ds) DNA and RNA, and RNA/DNA heteroduplexes in the 5'-to-3' direction. Plays a role in the RNA surveillance system in mitochondria; regulates the stability of mature mRNAs, the elimination of aberrantly shaped mRNAs and the rapid degradation of non technical processing intermediates.
