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.

Input: Consider Input:  Central ( heart rate , VE , VO2 ) or local ( muscle and blood lactate , adenosine triphosphate , creatine phosphokinase , glycogen ) cues highlighted in these studies demonstrate both the complexity of effort perception , and the need for better understanding of the physiological components upon which it is based .

Output: creatine phosphokinase


Input: Consider Input:  Vertebrate U6 small nuclear RNA ( snRNA ) loci exemplify a novel class of polymerase III - transcribed genes that lack an intragenic control region ( ICR ) .

Output: polymerase III


Input: Consider Input:  The potential biological significance of the identified structural motif shared by the human CCR5 , CCR3 , CCR2B and other GPCRs is discussed .


Output: human CCR5
