Identification of novel ubiquitous and cell type-specific factors that specifically recognize immunoglobulin heavy chain and kappa light chain promoters.

Abstract excerpt

In a search for novel factors that interact with the octamer element, immunoglobulin kappa light chain (V kappa) and heavy chain VH) gene promoters were compared for binding to nuclear proteins from lymphoid cells. Both promoters showed a similar pattern of bound factors, which was entirely different from that seen with the human immunodeficiency virus, type I promoter. Besides OTF-1 (Oct-1) and OTF-2 (Oct-2), at...
