Guanylate cyclase–activating proteins, 

bind to guanylate cyclase and stimulate its activity, elevating cGMP level and causing the cGMP-gated ion channels to reopen.

Humans CLRs that function as PRRs, most of which recognize one or more specific sugar moieties such as mannose (e.g., the mannose receptor and DC-SIGN), fucose (e.g., Dectin-2 and DC-SIGN), and glucans (e.g., Dectin-1).

Four Steps for bacterial transcription

1. Promoter search->closed promoter complex -> open promoter complex

2. Abortive transcription->Promoter Escape->Initiation from +1 TSS 

3. Elongation

4. Termination
