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.

Example 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 .
Example Output: gB glycoprotein

Example Input:  In contrast , postmitotic neurons possessed extremely low levels of E2F1 protein as assessed by the electrophoretic mobility shift assay and Western blotting .
Example Output: E2F1 protein

Example Input:  ER and DR were significantly correlated with MIB - 1 LI ( P < 0 . 01 and P < 0 . 05 , respectively ) , but RI and Td / Te were not .
Example Output:
MIB - 1
