The plasmid is confirmed by full-length sequencing.
GFPSpark Tag Information
GFPSpark is an improved variant of the green fluorescent protein GFP. It possesses bright green fluorescence (excitation/ emission max = 487 / 508 nm) that is visible earlier than fluorescence of other green fluorescent proteins. GFPSpark is mainly intended for applications where fast appearance of bright fluorescence is crucial. It is specially recommended for cell and organelle labeling and tracking the promoter activity.

HBP1 is a sequence-specific DNA-binding transcription factor. It is involved in many biological processes. It was reported that HBP1 binds to p16(INK4A) promoter and activates p16(INK4A) expression. We found that trichostatin A (TSA), an inhibitor of HDAC (histone deacetylase), induces p16(INK4A) expression in an HBP1-dependent manner. HBP1 activates or represses the expression of some specific genes during cell growth and differentiation. HBP1 was acetylated by p300/CBP in two regions: repression domain (K297/305/307) and P domain (K171/419). HBP1 acetylation after TSA treatment was confirmed by immunoprecipitation assay. HBP1 interacted with histone acetyltransferase p300 and CREB-binding protein (CBP) and also recruited p300/CBP to p16(INK4A) promoter. HBP1 acetylation at K419 plays an important role in HBP1-induced p16(INK4A) expression.
