In this task, you are given a sentence. You are expected to recognize the name of gene or protein. Although there might be several correct answers, you need to write one of them.

[Q]: The strongly DNA binding p50 subunit showed only very weak , if any , induction of gene expression .

[Q]: The present study also emphasizes the need of establishing dose - response curves to correctly assess the relative contribution of the different regions of steroid hormone receptors in activation of transcription .
[A]: steroid hormone receptors

[Q]: To understand this dramatic effect , we examined the localization of SR proteins and found that SC35 was shifted to the cytoplasm in sky1Delta yeast , although this phenomenon was not obvious with ASF / SF2 , indicating that nuclear import of SR proteins may be differentially regulated by phosphorylation .
[A]:
SR proteins
