Associate Editor(s)-in-Chief: Henry A. Hoff

Ndt80 is a meiosis-specific transcription factor required for successful completion of meiosis and spore formation.[1] The DNA-binding domain of Ndt80 has been isolated, and the structure reveals that this protein is a member of the Ig-fold family of transcription factors.[2] Ndt80 also competes with the repressor SUM1 for binding to promoters containing MSEs.[3]

Direct "binding of Ndt80 to the [mid sporulation element CRCAAAA/T (Ozsarac et al. 1997)] MSE is necessary for activating transcription of the middle sporulation genes."[4]

"The midsporulation gene SPR3 [...] is expressed only in sporulating cells (20), during both divisions of meiosis. It is therefore regulated in a developmentally specific manner and provides an example of a sporulation gene suited to analysis of midsporulation control. The 5􏰃'-flanking region contains several potential regulatory motifs, including an ABFI element which was shown to be essential to the regulation of SPR3 (33)."[5]

"The SPR3 gene contains four potential TATA boxes, with the most proximal one adjacent to the transcription start sites identified previously (33). The MSE is located 43 to 102 bp upstream of these TATA boxes, locating the sporulation-specific element very close to the site for assembly of the general transcription machinery."[5]

Interactions

MSE consensus sequences

Of the midsporulation element (MSE), "a minimal element, CRCAAA(A/T), is sufficient for sporulation specificity."[5]

"These genomic sequences were analysed for the presence of [...] middle sporulation elements (MSE) motif (5'-ACACAAA-3') using the NCBI BLAST tool."[6]

Middle sporulation elements (MSE) motif has the consensus sequence 5'-ACACAAA-3'.[6]

MSE (Branco) samplings

Copying apparent core consensus sequences for the MSEs of ACACAAA and putting it in "⌘F" finds none located between ZSCAN22 and none between ZNF497 and A1BG as can be found by the computer programs.

Comparison:

The occurrences of real MSE (Branco)s are greater than the randoms. This suggests that the real MSE (Branco)s are likely active or activable.
