UASt regulatory sequences drive expression of a K9M mutant of Hsap\H3-3A with C-terminal Tag:FLAG and Tag:HA flags.
Expression of Hsap\H3F3AK9M.Scer\UAS.T:Zzzz\FLAG,T:Ivir\HA1 under the control of Scer\GAL4da.PU results in suppression of position effect variegation (PEV) in both salivary glands and eye-antenna imaginal discs.
