Background
Protein lysine acyltransferase that can act as a acetyltransferase, glutaryltransferase, succinyltransferase or malonyltransferase, depending on the context. Acts as a histone lysine succinyltransferase: catalyzes succinylation of histone H3 on 'Lys-79' (H3K79succ), with a maximum frequency around the transcription start sites of genes. Succinylation of histones gives a specific tag for epigenetic transcription activation. Association with the 2-oxoglutarate dehydrogenase complex, which provides succinyl-CoA, is required for histone succinylation. In different complexes, functions either as an acetyltransferase (HAT) or as a succinyltransferase: in the SAGA and ATAC complexes, acts as a histone acetyltransferase. Has significant histone acetyltransferase activity with core histones, but not with nucleosome core particles. Acetylation of histones gives a specific tag for epigenetic transcription activation. Recruited by the XPC complex at promoters, where it specifically mediates acetylation of histone variant H2A.Z.1/H2A.Z, thereby promoting expression of target genes.
Usage guide
Shipping
In general, recombinant proteins are provided as lyophilized powder which are shipped with blue ice. Bulk packages of recombinant proteins are provided as frozen liquid which are shipped with dry ice.
Storage
Please avoid repeated freeze-thaw cycles. Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃ It is recommended that aliquot the reconstituted solution to minimize freeze-thaw cycles.
Reconstitution
Reconstitute at 250 μg/ml in sterile water.
