CECR2, a protein involved in neurulation, forms a novel chromatin remodeling complex with SNF2L. Human molecular genetics 2005 imex curation Banting GS., Barak O., Ames TM., Burnham AC., Kardel MD., Cooch NS., Davidson CE., Godbout R., McDermid HE., Shiekhattar R. Flag-SNF2L is human (See previous work PMID:14609955) The flag- CECR2 construct has been considered to be of human origin because the authors give the GenBank accession number of the human protein at the beginning of the paper (Q9BXF3). They identified it in a previous work. (ref 26). They say it encodes a 1464 amino acid protein which corresponds to Isoform C. hmcdermi@ualberta.ca Only protein-protein interactions human-293 Homo sapiens transformed primary embryonal kidney cells Human 293 Transformed human primary embryonal kidney cells.

The gene bank accession number that the authors give for RSF-1 protein is not correct (GenBank accession no. NP_009123) p160 and p180 protein bands were extracted, trypsinized and subjected to protein microsequencing for its identification. They corresponded to CECR2 and RSF-1 respectively.
