N2 - H2TF1 is a ubiquitous major histocompatibility complex (MHC) class I-specific transcription factor, which binds to the palindromic κB enhancer site upstream of MHC class I genes. Here we report that H2TF1 consists of a polypeptide with relative molecular mass 110,000, that corresponds to the predicted 100-kDa product (NF-κB2 p 100) encoded by the candidate proto-oncogene nfkb2 (lyt-10). H2TF1 was purified by a novel affinity chromatography method and identified as the NF-κB2 p100 polypeptide by peptide sequencing as well as by reactivity with a specific antiserum. Purified H2TF1 binds the MHC κB site with high affinity (KD = 3 × 10-11 M), in contrast with previous reports that NF-κB2 p100 did not bind DNA. * This work was supported by fellowship support of the Division of Hematology/Oncology, Brigham and Women's Hospital, a grant from the Medical Research Council of Canada, National Cancer Institute Grant K08-CA-01562-01 (to D.
