A little guide for advanced search:

Tip 1. You can use quotes "" to search for an exact expression.
Example: "cell division"
Tip 2. You can use + symbol to restrict results containing all words.
Example: +cell +stem
Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
Example: +cell -stem

e.g. searching for members in projects tagged cancer

Sequences of the sigma factors of Escherichia coli and Bacillus subtilis were aligned with the sequences of two sigma-like proteins, HtpR, involved in the expression of heat-shock genes in E. coli, and SpoIIG, necessary for endospore formation in B. subtilis. An internal region is highly conserved in the four proteins and is proposed to be involved in binding of sigma factors to core RNA polymerase. The carboxy-terminal part of the four proteins presents the characteristic structure found in several prokaryotic DNA-binding proteins and is proposed to be involved in promoter recognition.
