Identification of probabilistic transcriptional switches in the Ly49 gene cluster: a eukaryotic mechanism for selective gene activation.

abstract：:The current structural model of the B cell antigen receptor (BCR) describes it as a symmetric protein complex in which one membrane-bound immunoglobulin molecule (mIg) is noncovalently bound on each side by an Ig-alpha/Ig-beta heterodimer. Using peptide-tagged Ig-alpha proteins, blue native polyacrylamide gel electrop...
