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: Transient expression analyses in cells of neuroglial and lymphocytic origin demonstrated that some of these LTRs had activities which varied significantly from the LAI LTR in U - 373 MG cells ( an astrocytoma cell line ) as well as in Jurkat cells ( a CD4 - positive lymphocyte cell line ) .

Output: LAI LTR

Input: Consider Input: Bcl - 3 protein was also highly expressed in early burst - forming unit - erythroid ( BFU - E ) - derived erythroid precursors ( day 7 ) and decreased during maturation ( days 10 and 14 ) , suggesting that Bcl - 3 is involved in normal erythroid proliferation .

Output: Bcl - 3

Input: Consider Input: The functional effects of these interactions are that CBP and p300 , but not P / CAF , enhance EKLF ' s transcriptional activation of the beta - globin promoter in erythroid cells .
Output: P / CAF
