Research and Clinical Interests

We study the subcellular mechanisms through which MAPKs transduce environmental extracellular signals. My previous work identified and characterized SEK1/MKK4, the first known activator for the SAPK/JNK enzyme. We are now focusing on ERK3/MAPK6. ERK3 is enriched in the developing nervous system and is restricted to vertebrates. To dissect the regulation and function of ERK3, we are employing a multidisciplinary approach which includes biochemistry, genomics and cell biology.
