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:
We analyzed the effects of light on tubulin mRNA abundance in Arabidopsis seedlings using RNA gel blot hybridizations and gene - specific probes .

Ex Output:
tubulin mRNA

Ex Input:
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 .

Ex Output:
TIMP - 1

Ex Input:
Highly significant similarities were detected between the N - terminal region of P30 and those of GENA [ the product of another unidentified gene ( geneA ) located upstream of the aceEF - lpd operon ] , and GNTR ( a putative transcriptional repressor of the gluconate operon of Bacillus subtilis ) .

Ex Output:
gluconate operon
