title: Chromosomal localization of the genes encoding the p50/p105 subunits of NF-kappa B (NFKB2) and the I kappa B/MAD-3 (NFKBI) inhibitor of NF-kappa B to 4q24 and 14q13, respectively.
abstract: The regulation of expression of a variety of genes involved in immune function, inflammation, and cellular growth control, as well as control of expression of certain viruses such as the human immunodeficiency virus (HIV), is dependent on the transcription factor NF-kappa B. In many cells, NF-kappa B is found in the cytoplasm where it is associated with an inhibitor protein known as I kappa B. Recently the genes encoding the p50 and p65 subunits of NF-kappa B, as well as one form of I kappa B/MAD-3 (NFKBI), have been cloned. As part of our goal to determine the chromosomal organization of members of the REL/NFKB family, as well as their inhibitors, we localized the NFKBp50/p105 (NFKB2) and I kappa B/MAD-3 (NFKBI) genes to human chromosome bands 4q24 and 14q13, respectively.
