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.

 Fulminant hepatic failure in these cases could be characterized by : ( 1 ) rapid decrease in serum alanine transaminase ( ALT ) level after discontinuation of ecarazine , ( 2 ) prolonged jaundice despite discontinuation of ecarazine , ( 3 ) high incidence of anti - nuclear antibody ( ANA ) ( 57 % ) , and ( 4 ) histological findings of extensive hepatocellular necrosis ranging from bridging necrosis to massive necrosis .
serum alanine transaminase

 Here we show that inhibition occurs with a NS1 - Rev chimera in which the 78 amino - terminal amino acids of the NS1A protein comprising its entire RNA - binding domain is deleted , thereby establishing that this carboxyl portion of the NS1A protein can function as an independent effector domain .
NS1A protein

 Mutational analysis of the IME2 UAS reveals two critical sequence elements : a G + C - rich sequence ( called URS1 ) , previously identified at many meiotic genes , and a newly described element , the T4C site , that we found at a subset of meiotic genes .
