TIF2/YJL138C Protein Information Help

Standard Name Tif2p 1
Systematic Name Yjl138cp
ORF Classification 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; TIF2 has a paralog, TIF1, that arose from the whole genome duplication (2, 3, 4, 5, 6, 7)
Name Description Translation Initiation Factor
Gene Product eIF4A
Predicted Sequence Formatted Sequence or sequence in FASTA format
Length (a.a.) 395
Molecular Weight (Da) 44,697
