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:  We have isolated a unique murine FLT3 cDNA that codes for a variant isoform of FLT3 , devoid of the fifth Ig - like domain , by comparison with the prototypic form .
Example Output: murine FLT3 cDNA

Example Input:  The consensus mammalian ER stress response element ( ERSE ) conserved among grp promoters consists of a tripartite structure CCAAT ( N9 ) CCACG , with N being a strikingly GC - rich region of 9 bp .
Example Output: grp promoters

Example Input:  The N - terminal sequence of the extracellular MEP20 , TKVAS , was found at aa 194 - 198 within the ORF .
Example Output:
extracellular MEP20
