| abstract |
Certain embodiments of the disclosure are directed to variant filamentous fungal cells, compositions thereof and methods thereof for increased production of one or more proteins of interest. More particularly, in certain embodiments, the disclosure is directed to variant filamentous fungal (host) cells derived from parental filamentous fungal cells, wherein the variant host cells comprise a genetic modification which enables the expression/production of a protein of interest (POI) in the absence of inducing substrate. In certain embodiments, a variant fungal host cell of the disclosure comprises a genetic modification which increases the expression of a variant activator of cellulase expression 3 (ace3) gene encoding an Ace3 protein referred to herein as Ace3-L. |
