✦ Synopsis

A genomic clone encoding prothymosin ~ (gene symbol: PTMA), a nuclear-targeted protein associated with cell proliferation, was isolated and the 5"-regulatory region subcloned and sequenced. Because of previously reported discrepancies between several cDNA clones and a genomic clone for prothymosin c~, we determined the sequence of the first exon and of a 1.7-kb region 5" to the first exon. The sequence of the genomic clone reported here corresponds to the published cDNA sequences, suggesting that the previously noted discrepancies may be due to genetic polymorphism in this region. In addition, our sequence data extend the known 5"-upstream sequence by an additional 1.5 kb allowing the identification of numerous, potential cis-acting regulatory sites. This 5"-flanking cloned probe permitted us to localize the protothymosin gene to chromosome 2 in humans.

Radiation-induced acute myeloid leukemias (AMLs) in the mouse are characterized by chromosome 2 deletions. Previous studies showed that a minimal deleted region (mdr) of ϳ6.5 cM is lost from one homologue in chromosome 2-deleted AMLs. An AML tumor suppressor gene is proposed to map within this mdr.

Protamines are sperm-specific proteins that replace histones in the nuclear chromatin of mature spermatozoa. A chromosomal localization of the genes coding for human protamines has been achieved by in situ hybridization. Two cDNA probes of 423 bp and 397 bp containing the entire coding sequence for
