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.

Example Input:  Stimulation of T lymphocytes results in a rapid increase in intracellular calcium concentration ( [ Ca2 + ] i ) that parallels the activation of Ca2 + - calmodulin - dependent protein kinase IV ( CaMKIV ) , a nuclear enzyme that can phosphorylate and activate the cyclic adenosine monophosphate ( cAMP ) response element - binding protein ( CREB ) .
Example Output: nuclear enzyme

Example Input:  In this model , CD8 alpha + Mac - 1 - DCs are supposed to be of lymphoid while CD8 alpha - Mac - 1 + DCs are supposed to be of myeloid origin .
Example Output: CD8 alpha

Example Input:  Thus , regulation of UK - like PAs in HMy2 and GM4672A cells differs with respect to the extent to which glucocorticoids inhibit constitutively expressed activator levels , as well as the possible contribution of glucocorticoid - inducible inhibitors to the regulatory process in GM4672A cells .
Example Output:
constitutively expressed activator
