This page displays every known transcription unit of this operon and their known regulation.


Transcription unit          
Name: cspA
Gene(s): cspA   Genome Browser M3D Gene expression COLOMBOS
Note(s): cspA gene expression is repressed by MetJ, which is a protein that appears to bind to a site upstream of this gene, but it is not known which of two promoters (cspAp1, cspAp2) affects MetJ |CITS: [16515535]|.
The cspA gene was significantly upregulated in bacterial cells associated with lettuce roots in a microarray analysis |CITS: [22830299]|.
