In yeast, the transcriptional adaptor yeast Ada2 (yAda2) is a part of the multicomponent SAGA complex, which possesses histone acetyltransferase activity through action of the yGcn5 catalytic enzyme. yAda2, among several SAGA proteins, serves to recruit SAGA to genes via interactions with promoter-bound transcription factors. Here we report identification of a new human Ada2 homologue, hAda2bet...
Chronic obstructive pulmonary disease (COPD) has been defined by the Global Initiative for Chronic Obstructive Lung Disease (GOLD), as a disease state characterized by airflow limitation which is not fully reversible. COPD consists of emphysema which is the destruction and inflammation of the lung alveoli. Adenosine deaminase (ADA, E.C.3.5.4.4) converts adenosine to inosine. There are two isoen...
Human STAGA is a multisubunit transcriptional coactivator containing the histone acetyltransferase GCN5L. Previous studies of the related yeast SAGA complex have shown that the yeast Gcn5, Ada2, and Ada3 components form a heterotrimer that is important for the enzymatic function of SAGA. Here, we report that ADA2a and ADA2b, two human homologues of yeast Ada2, each have the ability to form a he...
In this report we described the cloning and characterization of ADA5, a gene identified by resistance to GAL4-VP16-mediated toxicity. ADA5 binds directly to the VP16 activation domain but not to a transcriptionally defective VP16 double point mutant. Double mutants with mutations in ada5 and other genes (ada2 or ada3) isolated by resistance to GAL4-VP16 grow like ada5 single mutants, suggesting...
IMPORTANCE Mutations in the CERC1 gene associated with deficiency in the ADA2 protein (DADA2) have been implicated in the pathogenesis of cutaneous polyarteritis nodosa (cPAN) and early-onset vasculopathy. DADA2 is not only limited to cPAN and vasculopathy but also includes immunodeficiency that affects several cellular compartments, including B cells; however, some patients appear to have a mo...
Abstract Background The deficiency of adenosine deaminase 2 (DADA2) is an autosomal recessively inherited disease resulting from loss‐of‐function mutations in ADA2, formerly named CECR1 (cat eye syndrome chromosome region, candidate 1) gene. Disease manifestations could be separated into three major phenotypes: inflammatory/vascular, immune dysregulatory, and hematologic; however, most patients...
