Protein

Cold shock protein CspB

Gene

cspB

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Binds to the pentamer sequences ATTGG and CCAAT with highest affinity in single-stranded DNA, and also to other sequences. Has greater affinity for ATTGG than CCAAT. Can act as transcriptional activator of cold shock genes by recognizing putative ATTGG-box elements present in promoter regions of genes induced under cold shock conditions.1 Publication

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
