small nuclear RNA activating complex, polypeptide 3, 50kDa
Small nuclear RNA-activating complex polypeptide 3
SNAPc 50 kDa subunit
SNAPc subunit 3
snRNA activating protein complex 50 kDa subunit
snRNA activating protein complex subunit 3
snRNA-activating protein complex 50 kDa subunit
snRNA-activating protein complex subunit 3
Part of the SNAPc complex required for the transcription of both RNA polymerase II and III small-nuclear RNA genes. Binds to the proximal sequence element (PSE), a non-TATA-box basal promoter element common to these 2 types of genes. Recruits TBP and BRF2 to the U6 snRNA TATA box.
Phosphorylated upon DNA damage, probably by ATM or ATR.
