PRP16/YKR086W Summary Help

Standard Name PRP16 1
Systematic Name YKR086W
Alias RNA16 2 , PRP23 3 , 4
Feature Type ORF, Verified
Description DEAH-box RNA helicase involved in second catalytic step of splicing and in exon ligation; exhibits ATP-dependent RNA unwinding activity; mediates the release of Yju2p and Cwc25p in the second step; in the absence of ATP, stabilizes the binding of Cwc25p to the spliceosome in the first catalytic step (5, 6, 7, 8)
Name Description Pre-mRNA Processing 4
