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]:  Upstream tissue inhibitor of metalloproteinases - 1 ( TIMP - 1 ) element - 1 , a novel and essential regulatory DNA motif in the human TIMP - 1 gene promoter , directly interacts with a 30 - kDa nuclear protein .
[A]: TIMP - 1


[Q]:  Central ( heart rate , VE , VO2 ) or local ( muscle and blood lactate , adenosine triphosphate , creatine phosphokinase , glycogen ) cues highlighted in these studies demonstrate both the complexity of effort perception , and the need for better understanding of the physiological components upon which it is based .
[A]: creatine phosphokinase


[Q]:  Moreover , our recent findings on the Tc52 encoding gene underline the interest of genetic manipulation of T . cruzi , not only making it possible to use more closely an in vitro approach to find out how genes function , but also to obtain ' attenuated ' strains that could be used in the development of vaccinal strategies .
[A]:
Tc52 encoding gene
