TIF1/YKR059W Summary Help

Standard Name TIF1 1, 2
Systematic Name YKR059W
Feature Type ORF, Verified
Description Translation initiation factor eIF4A; DEA(D/H)-box RNA helicase that couples ATPase activity to RNA binding and unwinding; forms a dumbbell structure of two compact domains connected by a linker; interacts with eIF4G; protein abundance increases in response to DNA replication stress; TIF1 has a paralog, TIF2, that arose from the whole genome duplication (3, 4, 5, 6, 7, 8)
