Nucleotide sequence of the gene for human transition protein 1 and its chromosomal localization on chromosome 2.

Transition protein 1 (TNP1) is a highly basic nuclear protein of 54 amino acids that is found in haploid spermatogenic cells during the period of transition of histones to protamines. Using the cDNA clone for human TNP1, we have isolated the gene encoding human TNP1 from human genomic libraries. The gene contains an intron of 200 bp; 1104 bp of the 5'- and 276 bp of the 3'-noncoding region have been sequenced. Comparison with the rat TNP1 gene yielded a similarity of 77% over the region between the transcription start point and the polyadenylation signal. The gene contains typical CAAT and TATAA boxes at conventional distances from the transcriptional start site. Using a series of human-rodent somatic cell hybrids containing variant complements of human chromosomes, the TNP1 gene was found to cosegregate with human chromosome 2. By in situ hybridization, the gene was assigned to the q35 and q36 bands of the long arm of chromosome 2. This chromosomal region encodes several genes, including TNP1, that are located on murine chromosome 1.[1]
