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.

Ex Input:
 When a longer - 714 to + 78 fragment of the PBGD promoter is used , the - 70 GATA mutant still displays erythroid - specific activity and is cis - activated by the 5 ' HS - 2 enhancer , while the - 100 CCACC mutant is completely inactive in the absence or in the presence of the 5 ' HS - 2 enhancer .

Ex Output:
PBGD promoter
