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:
 Interestingly , unlike PAK65 , HPK1 does not contain the small GTPase Rac1 / Cdc42 - binding domain and does not bind to either Rac1 or Cdc42 , suggesting that HPK1 . activation is Rac1 / Cdc42 - independent .

Ex Output:
small GTPase


Ex Input:
 Searching the human DNA data base of expressed sequence tags ( EST ) revealed novel partial sequences similar to , but distinct from , the sequences of the previously known PEF proteins .

Ex Output:
PEF proteins


Ex Input:
 In contrast , the holo - dTFIIA ( L / S ) binds TBP with high affinity .

Ex Output:

holo - dTFIIA
