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:  Two coxsackievirus B3 ( CVB3 ) variants ( H3 and H310A1 ) differ by a single amino acid mutation in the VP2 capsid protein .
Example Output: VP2 capsid protein

Example Input:  15 - Deoxy - Delta ( 12 , 14 ) - PGJ ( 2 ) ( 15d - PGJ ( 2 ) ) , a PPAR - gamma agonist , has a dose - dependent antiproliferative and cytotoxic effect on normal and malignant B cells as shown by [ ( 3 ) H ] thymidine and 3 - [ 4 , 5 - dimethylthiazol - 2 - yl ] - 2 , 5 - diphenyltetrazolium bromide assays .
Example Output: PPAR - gamma

Example Input:  In contrast , the synthetic progestins related structurally to 19 - nortestosterone , norethisterone and d - norgestrel , were virtually devoid of binding affinity towards the glucocorticoid receptor nor did they measurably influence the in vitro lymphocyte functions .
