| abstractText | TESK1 (testis-specific protein kinase 1) is a protein serine-threonine kinase, containing characteristic structural features composed of an N-terminal kinase domain and a C-terminal proline-rich domain. Tesk1 mRNA is predominantly expressed in testicular germ cells, and developmental changes of expression in mouse testis suggest a role for this kinase in spermatogenesis. In the present study, we isolated and determined the overall sequence of the mouse Tesk1 gene, which spans 6.1 kilobases (kb) and contains 10 exons and 9 introns. The protein kinase domain is located in exons 1-9, while the proline-rich domain is in exons 9 and 10. The deduced 627 amino acid sequence of mouse TESK1 shows 97% and 94% identity with the rat and human TESK1, respectively. Sequence of the 5'-flanking and -untranslated region is devoid of a TATA box, but does contain several potential binding sites for transcription factors, including Sp1, AP- 1, c-Myc, SRY and CREM (cyclic AMP-responsive element modulator). As CREM is implicated in the activation of several male germ cell-specific genes, it is suggested that the expression of the Tesk1 gene is under the control of CREM transcription activity. The Tesk1 gene was mapped to mouse chromosome 4A5-Cl by fluorescence in situ hybridization. (C) 1998 Elsevier Science B.V. |
