Structural highlights
FunctionCAS2A_SACS2 CRISPR (clustered regularly interspaced short palindromic repeat), is an adaptive immune system that provides protection against mobile genetic elements (viruses, transposable elements and conjugative plasmids). CRISPR clusters contain sequences complementary to antecedent mobile elements and target invading nucleic acids. CRISPR clusters are transcribed and processed into CRISPR RNA (crRNA). Involved in the integration of spacer DNA into the CRISPR cassette (By similarity). Functions as a ssRNA-specific endoribonuclease, producing a 5'-phosphomonoester and a 3'-hydroxy. Does not process pre-crRNA in the manner expected if it were the CRISPR-processing endoribonuclease. Prefers U-rich substrates and often cuts between adjacent U residues in regions predicted to be single-stranded. RNAs as short as 10 residues can serve as substrate.[1] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedThe Scottish Structural Proteomics Facility was funded to develop a laboratory scale approach to high throughput structure determination. The effort was successful in that over 40 structures were determined. These structures and the methods harnessed to obtain them are reported here. This report reflects on the value of automation but also on the continued requirement for a high degree of scientific and technical expertise. The efficiency of the process poses challenges to the current paradigm of structural analysis and publication. In the 5 year period we published ten peer-reviewed papers reporting structural data arising from the pipeline. Nevertheless, the number of structures solved exceeded our ability to analyse and publish each new finding. By reporting the experimental details and depositing the structures we hope to maximize the impact of the project by allowing others to follow up the relevant biology.
