功能： disease:Defects in HSF4 are the cause of lamellar cataract [MIM:116800]; also known as Marner type cataract (CAM). Lamellar cataract is an autosomal dominant common type of infantile cataract. Finger malformation is observed in some kindreds.,function:DNA-binding protein that specifically binds heat shock promoter elements (HSE). Isoform HSF4A represses transcription while the isoform HSF4B activates transcription.,PTM:Isoform HSF4B is constitutively sumoylated. Sumoylation represses the transcriptional activity and is promoted by phosphorylation on Ser-299. HSFA is not sumoylated.,PTM:Phosphorylated mainly on serine residues. Phosphorylation on Ser-299 promotes sumoylation on Lys-294.,similarity:Belongs to the HSF family.,subunit:Homotrimer. Exhibits constitutive DNA binding and forms trimers even in the absence of stress. Interacts with DUSP26, MAPK1, MAPK2 and MAP kinase p38.,tissue specificity:Expressed in heart, skeletal muscle, eye and brain, and at much lower levels in some other tissues.,
