|PROSITE documentation PDOC51204 [for PROSITE entry PS51204]|
The helicase/SANT-associated (HSA) domain is a predicted DNA-binding domain of ~75 amino acids , which is found in the eukaryotic SRCAP/p400/DOM and SNF2/brahma families . While each family has the core sequences that define the HSA domain, they each also have additional sequences that distinguish these families from one another. For example, the sequence HWDY(L/C)EEEM(Q/V) is found in the SRCAP/p400/DOM family, whereas the sequence HQE(Y/F)LNSILQ is found in the SNF2 /brahma family . In addition to the SANT and helicase (see <PDOC51192>) domains, the HSA domain is also found in association with bromo (see <PDOC00550>) .
Some proteins known to contain a HSA domain are listed below :
The profile we developed covers the entire HSA domain.Last update:
