The second extracellular loop (EL2) of rhodopsin forms a cap over the binding site of its photoreactive 11-cis retinylidene chromophore. A crucial question has been whether EL2 forms a reversible gate ...
Environmental and endogenous signals, including light, temperature, brassinosteroid (BR), and gibberellin (GA), regulate cell elongation largely by influencing the expression of the ...
Id proteins are negative regulators of basic helix–loop–helix transcription factors, which are critical for expression of genes associated with cellular differentiation. Previous studies have shown ...
