Extended analysis of the region encompassing the PRM1-->PRM2-->TNP2 domain: genomic organization, evolution and gene identification

Abstract

The human male haploid expressed protamine 1 (PRM1)-->protamine 2 (PRM2)-->transition protein 2 (TNP2) locus comprises a coordinately regulated multigenic domain. This region of 16p13.13 has been used as a model to address how the organization of genes and genic domains within the human genome may influence tissue specific gene expression. Toward this goal, we have completed an extensive computational and biological analysis of the region encompassing the PRM1-->PRM2-->TNP2 domain. These analyses have revealed the likely genesis of this domain. Interestingly, the SOCS-1 gene and an hnRNPC-class pseudogene lies just 3' of this domain. Regions of nuclear matrix attachment also mark these newly identified genes.
