"To ascertain whether one or both of these two ALS-GAS sites were functionally important for GH stimulation of ALS promoter activity, plasmids containing block mutations of either ALS-GAS1 [...] or ALS-GAS2 [...] were prepared in the context of the luciferase construct retaining full responsiveness to GH [...], and transfected into H4-II-E cells [...]. Mutation of the ALS-GAS1 element abolished the ability of the promoter to respond to GH [...]; mutation of the ALS-GAS2 element was without effect. Thus, an intact ALS-GAS1 element is necessary for GH stimulation of ALS promoter activity."[1]

Interactions

Consensus sequences

"Computer analysis of the nt −653 to nt −483 region identified two sites that resemble the [γ-interferon activated sequence] GAS consensus sequence, TTNCNNNAA (19). Similar GAS-like sites have been shown to mediate the effects of various cytokines, including [growth hormone] GH, on the transcription of other genes (19, 20). The first site, TTCCTAGAA (ALS-GAS1), is located between nt −633 and nt −625; the second site, TTAGACAAA (ALS-GAS2), is located between nt −553 and nt −545."[1]
