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:  B and C1 fusions with yeast GAL4 DNA - binding and transcriptional activation domains were also found to interact when synthesized and assayed in yeast .
Example Output: C1 fusions

Example Input:  The RsmA - mutant , like its parent , produces N - ( 3 - oxohexanoyl ) - L - homoserine lactone ( HSL ) , a starvation / cell density - sensing signal required for extracellular enzyme production .
Example Output: RsmA - mutant

Example Input:  The delta Mo + SV tumor DNAs from B - lineage tumors were typically rearranged at the immunoglobulin gene loci and contained germ line configurations of the T - cell receptor beta gene .
Example Output:
immunoglobulin gene loci
