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:  The full - length cDNA was cloned and sequenced , and the inferred amino acid sequence was found to encode a novel protein , which we named cystatin M , with 40 % homology to human family 2 cystatins and similar overall structure .
Example Output: cystatin M

Example Input:  The two complexes were detected with a similar activation kinetics upon IL - 4 stimulation .
Example Output: IL - 4

Example Input:  Consistent with this hypothesis , stimulation of A ( 2A ) - R or PKA enhanced nuclear aPKC activity .
Example Output:
nuclear aPKC
