TITLE Modular cis-regulatory organization of developmentally expressed genes: two genes transcribed tettitorially in the sea urchin embryo, and additional examples JOURNAL Proc. Natl. Acad. Sci. USA 93, 9322-9328 (1996) MEDLINE 96382464 COMMENTS 2.3 kb of DNA sequence extending upstream of the CyIIIa transcription start site is necessary and sufficient for correct spatial, temporal and quantitatively accurate expression of CyIIIa.CAT transgenes. Embryonoc expression of CyIIIa gene is controlled through interactions with at least 9 different transcription factors that bind at over 20 specific sites [1,2]. CyIIIa regulatory system consists of three complex modules. The proximal module (PM) interprets the specification functions by which the oral and aboral ectoderm (AE) and vegetal territories are established, and its function is to activate the CyIIIa gene in the AE late in cleavage [3,4]. This module is largely responsible for the whole early pattern of CyIIIa expression. The major positive input to the PM is yet uncharacterized P1 factor, which is active throughout the ectoderm. Expression is confined to the AE by the negatively acting SpP3A2 factor, which must become functional specifically in the oral ectoderm (OE) lineages [3]. The other positively acting factors SpOct, SpTEF1, CTF, that bind to the PM determine the level of expression and convey temporal information [3]. The middle module (MM) assumes the major role in controlling CyIIIa expression from the gastrula stage onward, driving the rate of expression to higher levels as the AE differntiates. The major positive input is provided by the SpRunt. Two different negatively acting factors, SpZ12-1 and SpMyb are required to confine expression to AE from the gastrula stage onward. The distal module of CyIIIA gene increases the output of either or both of PM and MM and contains clustered SpGCF1 sites. The PM and MM display at least three forms of interdependence: (i) some of the positively acting factors of the proximal module, particularly the CTF and the SpTEF1 boost the output of the middle module if their target sites also present in the construct. (ii) Some site in the PM, yet undefined is necessary for MM function in synthetic transgenes. (iii) The SpRunt1 interaction in the MM boosts the output of the PM early in development [3,4]. COMMENTS There is additional binding site for SpP3A2 factor in between SpZ12-1 and CTF-factor binding sites (i.e. in the region 1282 - 1620, which can be located at 1456 -1464 (identified by sequence inspection). This site is located in proximal module. There are several additional sites for SpGCF1 factor binding: one -in between CTF-factor and SpTEF1 (1790 - 1798 by sequence inspection), and two other around SpMyb factor binding site.
