Given the task definition, example input & output, solve the new input case.
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: Sox - 4 is important for very early B - cell differentiation , while TCF - 1 / LEF - 1 play a crucial role in early thymocyte development
Output: TCF - 1
The gene, TCF - 1 has been tagged as protein since it plays a crucial role in early thymocyte development.

New input case for you: 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 .
Output:
Tc52 encoding gene
