Task: Named Entity Recognition
Input (English):  Finally , the conservation of the two residues most sensitive to mutations ( Y949 and Y953 ) in TM11 , and in the homologous TM5 , of all mammalian P - gps and also in other ABC transporters , suggests that these residues and domains may play an important role in structural as well as mechanistic aspects common to this family of proteins .
Output (English): ABC transporters
