Research Description

Maya worked in the lab 2010-2011

In August 2011 Maya moved with her husband to Johnson City, TN.

She was focusing on the molecular mechanism of arrestin interaction with pro-apoptotic MAP kinase JNK3 using energy transfer-based methods in living cells. She was also trying to figure out how arrestin conformation and sub-cellular localization affect its ability to promote MAPK activation. The ultimate goal of these studies is to enable us to design arrestins that go to a particular cellular compartment and channel the signaling towards pro-apoptotic or pro-survival pathways in the cell.

Maya developed arrestin-3 mutant that acts as a dominant-negative silent scaffold: recruits the kinases of ASK1-MKK4-JNK3 pathway but does not facilitate JNK3 activation, thereby suppressing JNK3 signaling in the cell.

Maya published four papers form the lab:
