Gene
asiA
Protein
10 kDa anti-sigma factor
Organism
Enterobacteria phage T4
Length
90 amino acids
Function
Transcriptional inhibitor. Inhibits sigma 70-directed transcription by weakening its interaction with the core of the host's RNA polymerase. This allows Gp55 to successfully compete for the core enzyme. Plays an important role during the prereplicative period of phage T4 development.
