Analysis about the absolute number and fraction of articles from respective scientific journals that were used for the annotation of mammalian protein complexes in CORUM

Journal	Number of articles	Fraction of all articles (%)
The Journal of Biological Chemistry	253	23.6%
PNAS	76	7.1%
Molecular and Cellular Biology	65	6.1%
Cell	61	5.7%
Molecular Cell	55	5.1%
The EMBO Journal	52	4.8%
Nature	37	3.4%
The Journal of Cell Biology	34	3.2%
Science	24	2.2%
Total	1073	100%

Since some articles contain information about more than one protein complex, the number of articles is lower than the number of annotated complexes.
