RVB2/YPL235W Summary Help

Standard Name RVB2 1
Systematic Name YPL235W
Alias TIP49B 2 , TIH2 3 , TIP48 4
Feature Type ORF, Verified
Description ATP-dependent DNA helicase, also known as reptin; member of the AAA+ and RuvB protein families, similar to Rvb1p; conserved component of multiple complexes including the INO80 complex, the Swr1 complex, and the R2TP complex (Rvb1-Rvb2-Tah1-Pih1); involved in multiple processes such as chromatin remodeling, box C/D snoRNP assembly, and RNA polymerase II assembly (1, 2, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
