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.

Input: Consider Input:  By deletion analysis , we identified the regions of c - Jun encoding transformation and transactivation functions .

Output: c - Jun


Input: Consider Input:  Protease digestion and alkaline extraction of microsomes containing labeled mutant proteins further showed that segment 3 was sufficient for stable membrane anchoring of the glycoproteins , indicating that this segment may specify the transmembrane domain of the gB glycoprotein .

Output: gB glycoprotein


Input: Consider Input:  In an effort to identify factors involved in the expression of this important erythroid - specific regulatory protein , we have isolated the mouse EKLF gene and systematically analyzed the promoter region .


Output: mouse EKLF gene
