bp(MESH:Aging) decreases p(HGNC:AHSA1) View Subject | View Object

Since Aha1 levels are repressed in aging, but are abnormally preserved in AD, tau aggregation could be accelerated in part by Aha1 in the AD brain. PubMed:29311797

bp(MESH:Aging) decreases p(HGNC:AHSA1) View Subject | View Object

For instance, CyP40, FKBP52, PP5, Hop, p23, and Aha1 are all repressed in the aged brain. PubMed:29311797

path(MESH:"Cystic Fibrosis") association p(HGNC:AHSA1) View Subject | View Object

Previous studies have also implicated Aha1 for a role in cystic fibrosis. PubMed:29311797

p(HGNC:AHSA1) regulates act(p(FPLX:HSP90)) View Subject | View Object

As in the case of Hsp70, cochaperones of Hsp90, such as Aha1, cdc37 and TPR domain-containing proteins, regulate its ATPase activity and control its conformational transitions (reviewed in [84]). PubMed:21882945

p(HGNC:AHSA1) increases rxn(reactants(a(CHEBI:ATP)), products(a(CHEBI:"phosphate(3-)"), a(CHEBI:ADP))) View Subject | View Object

In addition, Hsp90’s hydrolysis of ATP, which is stimulated by Aha1, facilitates polypeptide release [82,106] and transfer to CHIP or other E3 ligases [107,108] PubMed:21882945

p(HGNC:AHSA1) increases complex(a(CHEBI:polypeptide), p(HGNC:STUB1)) View Subject | View Object

In addition, Hsp90’s hydrolysis of ATP, which is stimulated by Aha1, facilitates polypeptide release [82,106] and transfer to CHIP or other E3 ligases [107,108] PubMed:21882945

p(HGNC:AHSA1) increases act(p(FPLX:HSP90), ma(GO:"ATPase activity")) View Subject | View Object

The activator of Hsp90 ATPase homolog 1 (Aha1) works as a co- chaperone to stimulate the ATPase function of Hsp90 to regulate the folding and activation of client proteins. PubMed:29311797

p(HGNC:AHSA1) increases a(HBP:"Tau oligomers") View Subject | View Object

In the same study, we found that high levels of Aha1 in a tau transgenic mouse model increased tau oligomers as well as neuronal loss concomitant with cognitive deficits (Shelton et al., 2017). PubMed:29311797

p(HGNC:AHSA1) increases bp(GO:"neuron apoptotic process") View Subject | View Object

In the same study, we found that high levels of Aha1 in a tau transgenic mouse model increased tau oligomers as well as neuronal loss concomitant with cognitive deficits (Shelton et al., 2017). PubMed:29311797

p(HGNC:AHSA1) increases a(HBP:"Tau aggregates") View Subject | View Object

Since Aha1 levels are repressed in aging, but are abnormally preserved in AD, tau aggregation could be accelerated in part by Aha1 in the AD brain. PubMed:29311797

p(HGNC:AHSA1) association path(MESH:"Cystic Fibrosis") View Subject | View Object

Previous studies have also implicated Aha1 for a role in cystic fibrosis. PubMed:29311797

p(HGNC:AHSA1) increases act(p(FPLX:HSP90), ma(GO:"ATPase activity")) View Subject | View Object

The activator of Hsp90 ATPase (Aha1) binds asymmetrically to the Hsp90 middle domain, stimulating ATP hydrolysis and inducing transition to the closed state (180, 181, 185, 190). PubMed:23746257
