Standard Name

cspE

Gene Synonym(s)

ECK0616, b0623, JW0618, gicA, msmC[1], msmC

Product Desc.

cold shock protein CspE[2]; transcription antiterminator and regulator of RNA stability[3]

Binds and melts RNA, involved in cold acclimation; binds ssDNA; high copy protects the chromosome from decondensation by camphor and increases DNA supercoiling; dimeric[4]

Notes

[back to top]


The cspABEG deletion BX04 is cold-sensitive and forms filaments at 15C (Xia, 2001). CspE is a cold shock protein homolog, but is constitutively expressed at 37C. CspE has transcription antitermination activity. CspE affects rpoS and uspA expression. CspE is a negative regulator of cspA transcription. CspE binds ssDNA containing six or more contiguous dT residues with high affinity (Johnston, 2006).[4]
