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:  p107 induction of E2F DNA binding was observed primarily in S phase cells coincident with the increase in p107 protein levels .

Output: p107 protein


Input: Consider Input:  Analysis of pseudo VH gene segment recombination products reveals no bias in D gene segment reading frame utilization .

Output: D gene segment


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
